Jolt Official Field Manual

Offset Bends

Offset Calculator screen

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 amateur garbage.

1. 1Measure the distance to the obstruction, then measure how high you need to offset the conduit to clear it.
2. 2Open JOLT™ → Conduit Bending → Offsets.
3. 3Enter the offset height and your bend angle (10°, 22°, 30°, 45°, or 60°).
   Pro Tip: If you’ve got a pipe to clear, measure to the top of the pipe plus a little extra. If clearing the pipe takes 3 inches, tell JOLT™ you need a 4-inch offset. Assume the plumbers or HVAC guys might come back and wrap insulation on that pipe.
4. 4JOLT™ gives you the distance between marks and the shrinkage to subtract from your measurement.
5. 5Tap The Math to see the exact formula with your numbers plugged in.
6. 6The results card shows the Multiplier in amber — the number JOLT™ used to calculate your mark distance. Knowing the formula behind the number is how you level up fast.

3-Bend Saddle

3-Bend Saddle Calculator screen

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.

1. 1Open Jolt → Conduit Bending → 3-Bend Saddle.
2. 2Enter the obstacle height and the distance from your reference point to the center of the obstacle.
3. 3Jolt hands you the three mark locations and the bend angles for each.
4. 4Tap The Math to see the exact formula with your numbers plugged in.

Rolling Offset

Rolling Offset Calculator screen

A rolling offset moves conduit in two directions at once — both up/down and left/right — in a single pair of bends. This is the most spatially complex bend you’ll make. Without a calculator, you’re doing trigonometry on a piece of cardboard. With Jolt, it takes 10 seconds.

1. 1Open Jolt → Conduit Bending → Rolling Offset.
2. 2Enter the vertical rise (change in elevation) and the horizontal roll (change in side-to-side position).
3. 3Jolt calculates the true offset distance and spits out the exact marks and shrinkage.
4. 4Tap The Math to see the exact formula with your values plugged in.
5. 5The results card shows the Multiplier in amber.

Stub-Up (90° Bend)

90° Stub-Up Calculator

A standard 90-degree bend that kicks the conduit from horizontal to vertical. The only hard part is accounting for the bender’s “take-up” — the chunk of conduit eaten up by the radius of the bend.

1. 1Open JOLT™ → Conduit Bending → Stub-Up.
2. 2Enter your desired stub height in inches (it takes fractions like 12 1/2).
3. 3Select your conduit type and size. JOLT™ automatically applies the correct take-up (e.g., 16″ for 2″ conduit).
4. 4JOLT™ hands you the exact Bender Mark Distance to measure from the end of the conduit.
5. 5Tap The Math to see the exact formula with your values plugged in.

Conduit Fill Calculator

Swaps between electrical and measurement units fast. Need to turn millimeters into inches, or figure out how many watts a horsepower is? This does it.

1. 1Open JOLT™ → Calculators → Unit Converter.
2. 2Pick the category and what you’re converting (e.g., Length: Millimeters ↔ Inches).
3. 3Type a number on either side to get the answer.

Ohm’s Law Calculator

Calculates Voltage (V), Current (I), Resistance (R), or Power (W) when you only know two of the numbers. You need this for troubleshooting dead circuits or sizing components.

1. 1Open JOLT™ → Calculators → Ohm’s Law.
2. 2Enter any two numbers you know (e.g., 120V and 15A).
3. 3JOLT™ instantly spits out the missing values (e.g., 8Ω and 1800W).

Voltage Drop Calculator

Calculates how much voltage you’re losing over a long wire run because of the wire’s natural resistance. The NEC wants a maximum 3% drop for branch circuits.

1. 1Open JOLT™ → Calculators → Voltage Drop.
2. 2Enter wire material (Copper/Aluminum), wire size (AWG), voltage, phase, distance, and load (Amps).
3. 3JOLT™ gives you the voltage drop percentage and the actual voltage at the end of the run.

Set it once and the app remembers it.

Offset

Two bends of the same angle that elevate the conduit over an obstacle while keeping the run parallel. You define it by the offset height and the bend angle.

3-Bend Saddle

Three bends that arch the conduit over an obstacle. The center bend is twice the angle of the two outer bends. You use this when you can’t cut the conduit run.

Rolling Offset

A two-bend offset that moves the conduit up/down and left/right at the same time. You have to calculate the true offset distance from the rise and roll to get this right.

Stub-Up

A standard 90-degree bend turning the conduit from horizontal to vertical. You measure the stub height from the back of the bend to the end of the conduit. Subtract the bender’s take-up from your mark.

Take-Up

The chunk of conduit eaten up by the radius of a 90-degree bend. It changes based on conduit size and what bender you’re using. Jolt does this math for you in the stub-up calculator.

Shrinkage

How much your total run length shrinks when you put an offset bend in it. Subtract this from your layout measurement or your conduit will come up short.

Ohm’s Law

The math that runs everything: V = I × R. Power (W) = V × I. Learn it. Use it every day.

Voltage Drop

How much voltage you lose over a long wire run because of the wire’s resistance. The NEC wants a max of 3% drop for branch circuits.

AWG

American Wire Gauge. Lower number = fatter wire = more amps. Common sizes: 14, 12, 10, 8, 6, 4, 2, 1/0.

Ampacity

The maximum continuous current a wire can carry before the insulation starts melting. Depends on gauge, insulation type, and ambient temperature.

NEC

National Electrical Code. The rulebook. Updated every three years. JOLT™ has the 68+ essential codes you actually need, including the 2023 and 2026 changes.

GFCI

Ground Fault Circuit Interrupter. Trips in 1/40th of a second to keep you from getting electrocuted. Required near water — bathrooms, kitchens, garages, outside.

AFCI

Arc Fault Circuit Interrupter. Detects dangerous arcing in the walls that causes fires. Required in bedrooms and living areas in new construction.

LOTO

Lockout/Tagout. OSHA rules for killing power before you work. Your personal lock goes on the breaker so nobody can turn it back on while your hands are in the box.

NCVT

Non-Contact Voltage Tester. Your “hot stick” or “tick tracer.” Beeps and flashes near a live wire. Use it to prove a circuit is dead before you touch it.

EMT

Electrical Metallic Tubing. Thin-wall steel conduit used everywhere in commercial work. Easy to bend, uses set-screw or compression fittings. Keep it out of the dirt and concrete unless it’s protected.

Overcurrent Device

A breaker or fuse that trips when it gets too hot. You size it to protect the wire, not the equipment. 12 AWG wire gets a max 20A breaker. Period.

Pictorial Diagram

A 3D picture showing the actual devices and where the wires physically go. Way easier to read than a schematic when you’re actually wiring the box.

Conductor Color Code

120/240V: black/red = hot, white = neutral, green/bare = ground. 208V 3-phase: black/red/blue = hot. 480V 3-phase: brown/orange/yellow = hot.
