No. 12 gauge wire is rated for a maximum of 20 amps. You need a minimum of 10AWG wire for 30 amps.
How far can you run 10 gauge wire for 30 amps?
#10 is normally used for short runs of 30 amps. With 150 feet though, I'd opt at least for #8, and maybe even #6. Go to any standard wire table to find the ohmage of the wire size. Then you can calculate the voltage loss at 30 amps and see if you can tolerate that.
What size wire holds 30 amps?
10-gauge wire
How far can you run 8 gauge wire for 30 amps?
Go to any standard wire table to find the ohmage of the wire size. Then you can calculate the voltage loss at 30 amps and see if you can tolerate that. If so, #8 will probably work. For 150 feet though, I think I would opt for #6 to help with potential starting loads, etc.
How far can 10 gauge wire run?
How Far Can You Run 10 Gauge Wire? You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet. After these distances, the circuit will go over the recommended 3% voltage drop.
How far can you run a 30 amp wire?
30 amps carried over a 10 gauge wire is not meant to be run over far distances. If you plan on going over 150 feet, you should upgrade the wire size from 10 gauge to 8 gauge.
How far can you run 10 gauge wire before voltage drop?
You should not use a 30-amp circuit breaker on a 12-gauge wire. The circuit breaker installed on a circuit is of a specific size to protect a certain wire gauge. This higher current can damage the thinner wire, melt the insulation, cause short circuits, fire, and even lethal shock.
How many amps can 12-2 wire carry?
20
Can 12-2 Romex handle 30 amps?
Yes, based on the National Electric Code or NEC, you can use 12-2 AWG cables for THHN or THWN-rated wires. These cables are made for general purposes and can hold up to 194 degrees without taking any damage. It simply means these wires can withstand the heat temperature drawn by a 30 amp circuit breaker.
What wire do I need for 240v 30 amp?
10-gauge
What size wire do I need for a 30 amp 220V circuit?
Any circuit fused for 30 amps must use a minimum of 10 ga copper or 8 ga alu.
