Updating light switches

An electrician is often needed to make a good repair in such cases.In everything I have said above, I am assuming power is off while things are replaced.However, because connection mistakes are so possible, have a strategy for checking your work as you proceed.For instance, do one room at a time, replacing outlets and other items, then restore power, checking that everything works right there and also in nearby rooms before going on to the next room.The result will be: Don't connect any black to the green screw.That screw is meant to be given a (bare) ground wire attached to the bundle of grounds, if any, back in the electrical box.Even the replacing of light fixtures is not foolproof.Sometimes the wiring at a light box is passing the circuit through to various outlets in the area, so that care must be taken to connect everything back as it was.

Consult my diagrams relating to Three-way switches.Otherwise, you will have much more work to recheck later, with possibly more than one goof to complicate the picture.On the subject of upgrading electrical things in general, I have some words of advice about the electrical service upgrade, also known as an electrical service change or a panel change.Or a subpanel can be added and fed from spaces whose present circuits will be relocated to the subpanel.I’m trying to wire a GFI outlet in my bathroom then install a piggy back or double switch for two light switches with no success.
