## How do I calculate what size wire I need?

Wire Sizing Chart and Formula

1. Calculate the Voltage Drop Index (VDI) using the following formula:
2. VDI = AMPS x FEET ÷ (% VOLT DROP x VOLTAGE)
3. Determine the appropriate wire size from the chart below.

## Will 6 gauge wire fit in a 30 amp breaker?

RULES OF THUMB

“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”

## How far can I run 12 2 wire?

The total circuit would be about 60 -70 feet in length. It would only be supplying about 5 outlets and one light. It would be a light load, running small things, no heaters or med/large equipment. #12 provides reasonable performance up to about 100′ with general loads like you describe.

## How far can you run 10 2 wire?

The size of the wire you run to your shed depends on how far away it is and whether you use 120V or 240V. If your shed is 50 feet from your breaker box, you can use 10/2 AWG UF-B wire for a 120V circuit up to 20A. This will allow you to run multiple machines at the same time while providing light to your shed.
