  • What size wire for 250 amp power line?

  • This table says you need AWG 0000 to support 250 A if it is a bundled power line and AWG 00 if the wires are short and far apart (chassis wiring). It already does not look like just a wire, and you may easier find it where plain copper is for sale.

  • How many AWG wires do I need for 250 amps?

  • If you’re planning on operating something which requires 250 A continuously, you could run two 4 AWG wires to share the current. However, notice that your inverter probably does not have massive lugs to handle 0000 (quad-aught) or thicker gauge wire. In fact, it probably uses 0 (aught) gauge, if it’s similar to this Energizer EN3000 inverter.

  • How many amps can a 1/0 wire handle?

  • At 75C, it has a rated ampacity of 150 amps; essentially, the 1/0 W wire is a 150 amp wire size. At 60C, it can handle up to 125 amps, and it can handle up to 170 amps at higher temperatures (90C).

  • What is Maximum amps for chassis wiring?

  • The Maximum Amps for Chassis Wiring is also a conservative rating, but is meant for wiring in air, and not in a bundle. (Emphasis mine.)
