How many amps can 10 2 wire carry?
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 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.
Can you parallel #12 wire?
The National Electric Code only allows paralleling for conductors larger than 1/0. That is the basic reason that you cannot use 2 parrallel sets of #12 conductors to replace a number 10.
