## How far can you run 100 amp wire?

load calculations are for what minimum size panel/service needed but not the actual service rating if the breaker from the service side is a 100amp breaker feeding this then wire rated for 100 amp, etc. Most ampacity charts are up to 100 feet and go up one size of additional 100 feet.

## Can you run 110 on a 30 amp breaker?

Yes. Being a 30A circuit, you cant put 15 or 20A receptacles on it for other uses, so it has to be for the welder alone. Only a 5-30R receptacle is legal, though you can have more than one of them on that circuit, for convenience.

## How many wires can be in a 220 circuit?

A 220 volt outlet can take cables with 3 or 4 prongs. Not all 220 volt outputs use a neutral (white) cable, but all will have two hot wires (one red and one black) and a ground wire (green). For example, an air compressor requires 220 volts, but the socket has only three tips.

## What is code for buried electrical wires?

According to Section 12-012 of the code and table 53 the minimum depth without any protection must be 600 mm (or 24 in.). You must also bury caution tape above the depth of the wire so that if someone digs in the future they wont be shocked by their efforts. You might ask if this depth can be less than 24 inches.

## What size wire do I need to run 100 amps 300 feet?

for 300 feet for 100 amp rated service I would use Aluminum direct burial 1/0-1/0-1/0-1/0, the forth can be as low as #4 for the ground (but also in conduit, even if in conduit must still be rated underground wire and required by code also) Also note the size wire the breaker can handle, cannot cut strands to make fit,
