Electrical Service For The Garage
I had a garage built and am wiring the building with 200A service
myself. At Lowe's, they have a sign that says the lead-in cabling for 200A service needs to be 4/0 - 4/0 - 4/0 - 2/0 aluminum cable. But, one of their workers says that is wrong that the service cable must be that size, but in copper. Anyone know for sure? |

Get a qualifed electrician, since from your post I'm not sure if you want a new service, or a subpanel. later, tom @ www.Consolidated-Loans.info |

Is this cable to be used before or after the first disconnecting means? Is the service to your home to be single phase or three phase? Is the service supplied via overhead or underground conductors? -- Tom Horne "This alternating current stuff is just a fad. It is much too dangerous for general use." Thomas Alva Edison |

The cable will be before the first disconnect. It will lead from the
connection point where the electric company will provide service up to the meter base and then from there into the main breaker panel. The main service disconnect is on the main breaker panel. The service is three-phase and underground. Thanks Tom Horne, Electrician wrote: Rick wrote: I had a garage built and am wiring the building with 200A service myself.

The cable you described in your original post is suitable for the single phase feeder between the main disconnecting means and the lighting and appliance panel board/s in a residence but it is not allowed for the service entry conductors of a three phase two hundred ampere dwelling service. -- Tom Horne "This alternating current stuff is just a fad.

2/0 is sufficient for 200A in copper.
