for USA, Canada and countries running a 60 Hz power supply service.This is too involved to answer in a few short sentences. Get an electrician to do the work safely or a really good book on the subject.

One thing that most home owners don't understand, although the NEC is quite clear on this, is that if the sub-panel is in a detached building, it gets its own ground. You don't run a ground wire from the main panel to the sub-panel. Rather, you run only the neutral and two hots, and bond the neutral to the ground within the sub-panel, then ground it to an 8 foot long rod pounded into the ground, or other appropriate ground.

This is all quite different from the sub-panel being in the same building as the main panel. In that case, you run a separate ground wire, and don't bond the neutral and the ground at the sub-panel.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.

Before you do any work yourself,

on electrical circuits, equipment or appliances,

always use a test meter to ensure the circuit is, in fact, de-energized.

You will need a breaker in your house panel to protect the wire feeders that supply the panel in the garage. The terminology for this setup is called a sub panel. At the garage end you will need a disconnect at that panel as the garage is not attached to the house. You might want to consider a 100 amp combination panel at the garage as it has a built in main disconnect and spaces for 12 or 24 breakers depending on the size of panel you select.

Why would your power go out to your garage but not to your house and no fuses be blown?

Does the garage have a separate breaker box or fuse box inside? Is there a separate power feed for the garage? In the 70's and 80's some cities were allowing aluminum wiring INSIDE residences. If the wire from the main fuse/breaker panel is aluminum there is a real possibility that you might have a bad connection between the fuse box or breaker panel and the outlets in the garage.

How would you connect the wires to a 60A panel installed in a detached garage from a 200A panel in the house?

Assuming garage is detached less than 80 ft away. You need a 60 AMP double pole breaker for the 200 AMP house panel, and need to have two spare slots. Additionally you should have conduit in running in ground, and have #4/3 W/ground Stranded cable running to the sub panel. This setup will allow for 110V's and a 220V circuit. Connect the two hots, Red/Black to the Breaker on your servicing the panel. Connect the neutral (White) to the Neutral bus bar along with the Ground wire. Sub panel on detached Garage. Attach the White neutral wire to the Neutral ground bar. Attach the ground to the ground bar on the Sub panel. Pull the permits and have it inspected! If your house has the wires from the meter going straight into your panel box then you tie the neutral and ground to the same busbar. However; If you havve a disconnect on the outside of your house then you must separate the neutral andground inside the 200 amp panel box. This is usually prevalent on a mobile home or any time the pnel box you are using is fed from another panel or disconnect.


Can you install Electric meter on detached garage?

Question Needs Clarification!! If you are building a houseand you want the meter mounted on your detached garage to feed the house that is a question that your local utility or electrical inspector would hav to answer as it varies . If you want a meter on your garage that to would have to be answered by your utility as they have requirements about running service wires on residential property. they will probanly allow this as they usually charge more for having the service to a "commercial" building. The bse rate in my locality is twice that of a residential service. And even though it is your personal garage they consider it commercial in most places.

Where is the circuit breaker in a garage?

If your circuit breakers are in the garage, they would be in a electrical panel (a metal box mounted on a (usually) outside wall, with the electric meter on the outside. The circuit breakers can be either just below the meter on the outside on opposite it inside the garage. It would usually be very close to where the electric connection to the house is. The electrical panel and breakers are not necessarily in the garage.
