This Lexington, KY homeowner decided he was an electrician and set out to prove he wasn't. He succeeded.
He needed just a little more juice so he added a sub panel below the original panel.
Here's a view of the sub panel. Notice the neutral and ground wires on the same bus bar in the sub panel. Proper bonding and grounding is a problem issue for a lot of people.P
No strain relief clamps or bushings to protect the wires from the sharp edge of the box.
Cover plates on Junction Boxes? Who needs them.
Homeowners can (and do) perform a lot of work themselves. But, especially with electrical, they either need to make sure they really understand the whole concept or hire a professional electrician.
Electricity can kill you or burn down your house.
Know what you're doing or hire a real electrician.
