I'm going to be putting in a 200 amp service to my garage. I will be wiring 220v 20 amp breakers.
What gauge wire do I need for that? How many conductors do I need? Thanks |

What you need is a qualified electrician. No I don't. I know how the shit goes in the box. I just need to know what size. The inspector has to approve it before the power company will do their thing. If you don't have anything positive to add, don't add anything next time. |

Any other metallic paths between the buildings (phone, plumbing, etc)? You can get by with a 3-wire service to a separate building if there are NO other metallic paths between the buildings. If there are ANY other metallic connections (or you add one) a 4-wire connection is required. A separate building with more than one circuit requires a panel with grounding electrodes. Safety is better with a 4-wire service. |

What gauge wire do I need for that? How many conductors do I need? Are YOU actually doing the whole installation ? In Conduit ? Direct Burial ? Detached or attached garage ? Pulling the wire yourself ? Setting the panel ? Permit ? Is an inspection necessary ? Will your homeowner's insurance "stay" in effect ? I do not mean to offend, I do not mean to insult, and I do bow down to the spirit of good old "do-it-yourself". But ... (bear with me here) ...when you don't seem to have enough experience to own/use a NEC Code and look up conductor ampacities ... I get, at least a bit worried. OTOH ... you did say it is your garage.
