    I would like to run 240v to my garage. The plan is to install a sub-panel, inside the house where the A/C #8 wire exits. Will a sub-panel support the A/C compressor and 240v to the garage? Note: Currently the detached garage is fed by a 30A fuse (120v), ran through buried conduit...

    In a large bunkhouse we need to add a second range, water heater, and kitchen outlets. The existing panel is 125 AMP (with breaker), and don't want to redo entire panel. A consultant said to install a 200 AMP drop, with a panel to handle the additional load. Would you then feed each of the...

    I am running a 60A subpanel out to my new garage. I dug a trench and laid 2" PVC conduit from the basement to the garage. The issue I am having is that the main service panel in the basement is in a finished room, and I can't run rigid conduit to it. I will have to snake the wires through a...

    I've got a 100amp subpanel from a 200amp service planning on using #3 copper THHN. The nuetral bar on the main service is only large enough to handle #6. Can I run two #3 hots and two #6 nuetrals instead of two #3 hots and 1 #3 nuetral?
