Jolt Field Manual
Your complete guide to using every tool inside the JOLT™ app — from your first conduit bend to your final code check. Open Jolt, follow the steps, and get the job done right.
⚡ Safety First — Before You Touch Anything ALWAYS OPEN
▼
Our company’s purpose is to strengthen your hand, not to injure you or cause damage. In order to do that, please understand the following: working with electricity is inherently dangerous, if not potentially deadly. JOLT™ is designed to be used on live jobs. Before you pull up any tool in the app, run through this checklist. Every single time. No exceptions. The app can calculate anything — but it cannot protect you from energized conductors.
🔴 De-energize Before You Work
Electricity does not warn you. It does not give second chances. The steps below are not suggestions — they are the difference between going home and not going home.
Locate the correct breaker. Find the panel feeding the circuit you are working on. If labels are missing or unclear, use a non-contact voltage tester (NCVT) to trace the circuit before touching anything. Never guess.
Turn off the breaker and lock it out. Flip the breaker to OFF. If you have a lockout/tagout (LOTO) kit, apply it now. Hang your personal lock — no one removes it except you. If you do not have a LOTO kit, tape the panel door shut and write your name on the tape.
Test before you touch. At the device or junction box you are working on, test all conductors — black, white, and bare/green — with your NCVT. Test twice. A single beep means the circuit is still live. Do not proceed until all conductors test dead.
Verify your tester works. Before and after testing the circuit, test your NCVT on a known live outlet. If it does not beep on the live outlet, the tester’s battery is dead. Replace it before continuing.
Wear your PPE. Minimum: safety glasses and insulated gloves rated for the voltage you are working near. Arc flash gear is required for any work inside an energized panel. When in doubt, wear more protection, not less.
Tell someone. If you are working alone, let someone know where you are and what you are doing. If you are working in a commercial building, follow the facility’s permit and notification procedures.
How Jolt supports safety: The Jolt app’s Code Lens feature can instantly pull up the NEC section governing the work you are about to do — including required clearances, conductor sizing minimums, and grounding requirements. Use it before you start, not after. Sparky AI can also answer “what are the safety requirements for [task]?” in plain language.
📐 Conduit Bending Tools 4 Tools
▼
Conduit bending is one of the most skill-dependent tasks in the trade. Jolt’s bending calculators remove the guesswork — you enter your measurements, Jolt gives you the exact marks, multipliers, and shrinkage values. The result looks like you have been bending pipe for 20 years.
Jolt Conduit Bending menu — four dedicated calculators
Offset Bends
Offset Calculator screen
What This Is
An offset is two bends of equal angle that elevate the conduit or change its path to clear an obstruction — a beam, a box knockout, a floor penetration. The two bends must be perfectly matched or the conduit will dog leg and look like dog shit (amateur).
Jolt Steps
- 1Measure the distance to the obstruction, then measure how far you need to change the direction of the conduit.
- 2Open JOLT™ → Conduit Bending → Offsets.
- 3Enter the offset height and your bend angle (10°, 22°, 30°, 45°, or 60°).
Pro Tip: If you have a pipe you need to clear, measure to the top of the pipe plus a little extra just to be sure. If clearing the pipe requires 3 inches, tell JOLT™ you need a 4-inch offset. That’s how a pro does it (assume they might come back to install 1 inch of insulation on the pipe you’re trying to clear).
- 4JOLT™ returns the distance between marks and the shrinkage to subtract from your measurement.
Field Execution
Mark your first bend point on the conduit. Measure the distance JOLT™ gave you and mark the second point. Place the bender’s arrow on the first mark, bend to angle. Do not flip the bender. Only rotate the pipe 180 degrees and move it to the next mark, then bend to the same angle. The conduit should lay flat with a clean parallel offset.
Lay a level across both runs — they should be parallel. The offset height should match your target measurement within ¼ inch.
3-Bend Saddle
3-Bend Saddle Calculator screen
What This Is
A 3-bend saddle straddles an obstacle — a pipe, a beam flange, a duct — without cutting the conduit run. Three bends create a smooth arch over the obstruction. The center bend is twice the angle of the two outer bends.
Jolt Steps
- 1Open Jolt → Conduit Bending → 3-Bend Saddle.
- 2Enter the obstacle height and the distance from your reference point to the center of the obstacle.
- 3Jolt returns the three mark locations and the bend angles for each.
Field Execution
Transfer Jolt’s marks to the conduit. Make the center bend first (the largest angle). Then make the two outer bends. Check that the saddle sits flat on both sides of the obstacle and clears the top cleanly.
The conduit should sit flat on both sides of the obstacle with no rocking. The arch should clear the obstruction by at least ½ inch.
Rolling Offset
Rolling Offset Calculator screen
What This Is
A rolling offset moves conduit in two directions simultaneously — both up/down and left/right — in a single pair of bends. This is the most spatially complex conduit calculation. Without a calculator, it requires trigonometry. With Jolt, it takes 10 seconds.
Jolt Steps
- 1Open Jolt → Conduit Bending → Rolling Offset.
- 2Enter the vertical rise (change in elevation) and the horizontal roll (change in side-to-side position).
- 3Jolt calculates the true offset distance and gives you the exact marks and shrinkage.
Field Execution
Transfer Jolt’s marks to the conduit. Make the first bend, then rotate the conduit to the required roll angle and make the second bend. Ensure the conduit clears the obstacle and maintains the correct trajectory.
Stub-Up (90° Bend)
90° Stub-Up Calculator
What This Is
A 90-degree bend that turns the conduit from horizontal to vertical. The challenge is accounting for the bender’s “take-up” — the amount of pipe consumed by the radius of the bend.
Jolt Steps
- 1Open JOLT™ → Conduit Bending → Stub-Up.
- 2Enter your desired stub height in inches (accepts fractions like 12 1/2).
- 3Select your conduit type and size. JOLT™ automatically applies the correct take-up (e.g., 16″ for 2″ conduit).
- 4JOLT™ returns the exact Bender Mark Distance to measure from the end of the conduit.
Field Execution
Measure from the end of the conduit and mark the distance JOLT™ provided. Place the bender’s arrow on the mark and bend to a full 90 degrees. Check with a level to ensure the stub is perfectly plumb.
🧮 Electrical Calculators 7 Tools
▼
Stop doing math on cardboard. Jolt’s calculators handle the complex formulas instantly so you can focus on the installation.
Ohm’s Law Calculator
What This Is
Calculates Voltage (V), Current (I), Resistance (R), or Power (W) when you only know two of the values. Essential for troubleshooting circuits or sizing components.
Jolt Steps
- 1Open JOLT™ → Calculators → Ohm’s Law.
- 2Enter any two known values (e.g., 120V and 15A).
- 3JOLT™ instantly calculates the missing values (e.g., 8Ω and 1800W).
Field Execution
Use your multimeter to verify the actual voltage or resistance in the field, then compare it against Jolt’s calculation to identify if a component is failing or drawing too much power.
What Happens If You Fuck This Up: If you ignore Ohm’s Law and put a 2000W heater on a 15A circuit, you will pull 16.6A and trip the breaker every time it turns on.
Voltage Drop Calculator
What This Is
Calculates how much voltage is lost over a long wire run due to the wire’s natural resistance. NEC recommends a maximum 3% drop for branch circuits.
Jolt Steps
- 1Open JOLT™ → Calculators → Voltage Drop.
- 2Enter wire material (Copper/Aluminum), wire size (AWG), voltage, phase, distance, and load (Amps).
- 3JOLT™ returns the voltage drop percentage and the actual voltage at the end of the run.
Field Execution
If Jolt shows a voltage drop exceeding 3%, upsize your wire gauge in the calculator until the drop is acceptable, then pull that larger wire for the run.
What Happens If You Fuck This Up: If you ignore voltage drop on a 500 ft run of wire to lights, the lights will be dim, they might flicker, and any motors on the circuit will burn out prematurely from undervoltage.
Conduit Fill Calculator
Conduit Fill Calculator screen
What This Is
The most advanced fill calculator on the market. It calculates the total cross-sectional area of your wires against the allowable fill percentage of the conduit (usually 40% for 3+ wires). Features Quick Presets (Branch Circuit, Service Entrance, Feeder), Minimum Conduit Sizing (tells you the smallest pipe that works), and Remaining Capacity (tells you how many more wires still fit).
Jolt Steps
- 1Open JOLT™ → Calculators → Conduit Fill.
- 2Use a Quick Preset or manually select conduit type/size and add your conductors.
- 3JOLT™ displays a circular gauge with the fill percentage.
Field Execution
Before pulling wire, verify your conduit size and conductor count against Jolt’s calculation. If you’re near 40% fill, use plenty of pulling lube and ensure your bends are smooth to prevent damaging the insulation.
What Happens If You Fuck This Up: If you overfill a pipe, you will strip the insulation off the wires while pulling them, creating a dead short inside the conduit.
Fraction / Tape Measure Calculator
Fraction Calculator screen
What This Is
Converts and calculates fractions exactly as they appear on a tape measure. No more converting to decimals in your head. Just add and subtract tape measure readings directly.
Jolt Steps
- 1Open JOLT™ → Calculators → Fraction Calculator.

- 3Enter your second measurement and tap Add or Subtract to get the exact result.
Field Execution
Take your measurements directly from your tape measure, punch them into Jolt, and use the exact result to mark your conduit or strut. No decimal conversion needed.
Blueprint Scale Calculator
Blueprint Scale Calculator screen
What This Is
Converts blueprint measurements to real-world dimensions instantly. Essential for doing takeoffs and estimating wire runs from architectural drawings.
Jolt Steps
- 1Open JOLT™ → Calculators → Blueprint Scale.
- 2Select the architectural scale shown on your blueprint (e.g., 1/4″ = 1′).
- 3Measure the distance on the blueprint with a ruler and enter the inches. JOLT™ shows the actual footage.
Field Execution
Lay your blueprint flat, verify the printed scale, and use your ruler to measure the run. Enter the inches into Jolt and use the resulting footage to pull the correct amount of wire off the spool.

📖 Field Terminology Appendix
▼
Every term in this manual is defined below. Click any term name to jump to the section where it is used.
Two equal-angle bends that elevate conduit to clear an obstacle while maintaining a parallel run. Defined by offset height and bend angle.
Three bends that arch conduit over an obstacle. The center bend is twice the angle of the two outer bends. Used when cutting the conduit run is not possible.
A two-bend offset that moves conduit in both the vertical and horizontal planes simultaneously. Requires calculating the true offset distance from the rise and roll dimensions.
A 90-degree bend turning conduit from horizontal to vertical. The stub height is measured from the bend to the end of the conduit. Bender take-up must be subtracted from the mark location.
The amount of conduit consumed by a 90-degree bend. Varies by conduit size and bender model. Jolt accounts for take-up automatically in the stub-up calculator.
The reduction in the measured run length caused by an offset bend. Must be subtracted from the layout measurement to maintain accurate conduit positioning.
The fundamental relationship between voltage (V), current (I), and resistance (R): V = I × R. Also expressed as I = V/R and R = V/I. Power (W) = V × I.
The reduction in voltage along a conductor due to its resistance. NEC recommends 3% maximum for branch circuits. Caused by long runs, undersized wire, or high current loads.
American Wire Gauge. The standard sizing system for electrical conductors in the United States. Lower numbers indicate larger wire diameter and higher ampacity. Common sizes: 14, 12, 10, 8, 6, 4, 2, 1/0.
The maximum continuous current a conductor can carry without exceeding its temperature rating. Determined by wire gauge, insulation type, and installation conditions (conduit fill, ambient temperature).
National Electrical Code. Published by NFPA (National Fire Protection Association) and updated every three years. The primary standard governing electrical installations in the United States. JOLT™ includes 68+ essential codes, including 2023 and 2026 NEC Changes.
Ground Fault Circuit Interrupter. A device that detects current imbalance between hot and neutral conductors (indicating a ground fault) and trips in as little as 1/40th of a second. Required in wet locations, bathrooms, kitchens, garages, and outdoors per NEC 210.8.
Arc Fault Circuit Interrupter. Detects dangerous arcing conditions in wiring that can cause fires. Required in bedrooms, living areas, and most habitable rooms in new construction per NEC 210.12.
Lockout/Tagout. An OSHA-required safety procedure for de-energizing equipment before maintenance. Involves applying a personal lock to the energy isolation point (breaker, disconnect) so it cannot be re-energized while work is in progress.
Non-Contact Voltage Tester. A pen-style tester that detects AC voltage without touching conductors. Beeps and/or lights when held near an energized conductor. Essential for verifying circuits are de-energized before working.
Electrical Metallic Tubing. Thin-wall steel conduit used in commercial and residential installations. Lighter than rigid conduit, easier to bend. Connected with set-screw or compression fittings. Cannot be used in concrete or underground without additional protection.
A breaker or fuse that interrupts current when it exceeds a safe level. Must be sized to protect the conductor, not the load. A 12 AWG conductor requires a maximum 20A overcurrent device per NEC 240.4.
A 3D illustration showing actual devices with wires in their physical positions. Easier to follow than schematic diagrams for installation work. Jolt’s 3D wiring diagrams are interactive pictorials.
NEC-required color identification for conductors. For 120/240V: black/red = hot, white = neutral, green/bare = ground. For 208V 3-phase: black/red/blue = hot phases. For 480V 3-phase: brown/orange/yellow = hot phases.
