What size cable do I need for 200 amps?
Wiring 200 amp service requires either #2/0 copper wiring or #4/0 aluminum or aluminum clad wiring. Which wire used is determined by the voltage drop and length of the wiring. Many electrical contractors opt to use #4/0 aluminum or copper-clad wire.
What size copper wire is good for 150 amps?

What size wire will carry 100 amps?
When it comes to the lines connecting master and secondary panels, where the line will carry as much as a full 100 amps, use a 2-gauge non-metallic sheathed electrical cable. The cable must contain one or two hot wires depending on your needs, one neutral wire, and one ground wire. Each wire should be 2-gauge in size.
What size wire do I need to run 100 AMP 200 feet?
For a 100 ampere circuit, the conductors will likely be required to be 3 AWG copper or 1 AWG aluminum. However, if you care about power quality, you’re going to want to increase the size of the conductors to reduce voltage drop.
What is wire size and ampacity?
Wire Size & Amp Ratings. Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.” You must use the correct size wire for the current (load) requirement of the circuit to prevent the wire from overheating.
What size wire do I need for a 12 amp outlet?
For every extra 50 feet of cable/wire up to #8 normally you upgradeto the next size, consult you local codes if your unsure about doubleand triple length runs. Ex: #6 is sometimes mandatory for a 200 foot 12 amp run but can be used up to 300 feet on a 12 amp circuit. Note:
What size cable should I get for cable sheath?
99.9\% of the time when you get into “insulated” #8 and bigger wire,it’s most likely going to be stranded (just like it’s big sister”Service cable”). You can usually get your basic sheathed xx/2 and xx/3cable up to 6 guage. If you need larger than #8 or #6 though, you willhave to buy service or “service type” cable. This can cause twoproblems.
