I have 200 amp box in house, the wall that the meter is on will have to be moved on the side of the attached garage wall what I would like to do is have both boxes, the house box and a 125 amp box in garage that would come off the meter.

Put a 125A CB in the main panel, pull a 4-wire to the garage panel....with any luck, neither panel will be over-loaded.


How did you arrive at the conclusion you need 125A in the garage?

"Hoping" doesn't do anyone any good...you over estimate what you need/require - you pay extra; you under estimate - you still pay extra.


Do a load calc. and KNOW.

How many tools can you actually run at the same time? I mean, 125 amps sounds like plenty, unless you have multiple people working at once, or a piece of equipment that draws a lot.

You have a good point the most I would run at one tims is 220 table saw the wife with furnis hot water heater micro wave tv should not run over 200 amps. I guess I'll go with a 60 amp CB.

In these cases I like to go with a 100 amp panel in the garage. They are so available, the price is right. And you get plenty of spaces. And a 100 amp branch breaker should be easy to find for your main panel.

I just read your post again and suddenly I am confused. What do you mean by "the main that is on the wall of the garage?" I caught the part where you said you wanted "both boxes" to be wired from this "main on the wall of the garage." Are you referring to the meter can? At any rate, you should install the feeder from your main 200 amp panel in the house to the new sub panel in the garage as celtic suggested.

If the SE in on the outside wall of the house where you are building the new garage/shop, does it have to be relocated? Do you need a bldg permit? I would check with the AHJ or POCO and check the requirements for the SE, then as others suggested run from the Main Panel to a sub in the shop.

FWIW I added a 400 sf add to my 24 x 30 garage for a shop.
radial arm, miter saw, thickness planer, table saw, frig, freezer, furnace, window a/c and general lighting and outlets, and a welder. just made it with a 125. Its detached, so has own SE and meter and gnd. I don't know about you, but I can only run one at a time and hope to turn out good stuff.

garage opener too.

OK you guys have helped a lot I knew about the sub panel box that would come off the main circuit breake box in the house, I thought there was another way to connect two boxes off the meter that way I would not need to feed off th e 200 amp in the house. Like you all said there will be only the wife and I should have enough amps for everything.

thanks happy new year... will gas ever go down to 1.00 a gallon????

I agree that 60 amperes would probably be enough but you should do load calc. and since it is residential shop not everything is running at the same time.
