What Size Aluminum Wire For 200 Amp Service
Recently, code has stated that the size of aluminum wire for a 200 amp service entrance must be 250 awg unless a demand load calculation can be completed to prove to the local inspection authority that the 4/0 conductor size does not exceed 185 amps of draw.
How many wires do I need for a 200 amp service?
Generally for a single phase installation it would be 3 wires. Two hot wires and a neutral. For a 3 phase installation it would be 4 wires.
What do I need for a 200 amp service?
There are a few things you need in order to have a 200 amp service. First, you’ll need a 200 amp electrical panel. Next, you’ll need wire and cable rated for your desired size of circuit. In this case, it needs to be 4/0 AWG wire or cable rated for 200 amps or less. Finally, you’ll need a ground rod, meter base and pipe oh yes and an electrician.
What size ground wire do I need for 200 amp service?
A ground wire is a bare copper conductor that is used to transfer fault current from the electrical system’s grounded parts to the earth in the event of a short circuit. A minimum of number 3 awg must be used in Canada.
