I'm replacing an existing Electrical Panel in my detached Shop. The existing Panel doesn't have a main. Installation of a 125A main doesn't allow for sufficient quantity of Breaker spaces to support all existing curcuits in the Shop. I'm installing a Square D (Homeline 125A) with an integral Main. This Panel is slightly larger than the one being replaced and the feeder Cable from the service in my attached Garage (1/0) is to short when I attach the existing branch curcuits (Lights, outlets ect). I'll have to replace either the feeder Cables or the initial lenght of each branch curcuit. Question: 1) Is there a min. - max height requirement for the Panel ? 2) Can I rotate the Square D Panel 180 Deg. ? If I can rotate the Panel (main on the bottom) all Wire is sufficient for length. The Plastic Breaker receptical is attached to the panel with a single Screw and (4) tabs.

Thanks

You can mount the panel with the main at the bottom.
Pay attention to the grounding requirements for a sub panel.Ideally,you should have a 4 wire feeder.

 

Yup, like Tex says, flip it over,, you see them all the time done that way and thats why. The electric will just have to work a bit harder to push up the buss instead of having gravity do its thing and letting it fall to the secondary breakers.

 

LOL @ sberry

 

Great Help Guys !!!

Thanks

PS: 4 Wire it is.
