Short for ampere, a unit of measure for current or the volume of electricity running through a circuit. The amp rating for a device or cable determines the amount of current it can safely handle. Typical household circuits begin at 15 amps and go up to 50 or 60 amps.
Insert a clamp, with wires attached, into the junction box hole and from inside the box, push the included nut over the wires and onto the clamp threads. Turn the nut as far as possible onto the threads and then use a screwdriver and hammer to tap it down until it’s tight.
First, plan the path for the new wiring and remove the baseboards where necessary. Use a sharp drywall knife to cut the caulk and paint sealing the top of the baseboard to the wall.
An easier alternative to repairing the damage is to use one coat of mud and then cover the rough repair with a preformed medallion. A plastic medallion can be installed using caulk to stick it to the surface or using the fixture cover plate to hold it in place. You can also get a plaster medallion, these should be installed using setting joint compound or plaster of Paris to attach it to the ceiling. Keep pressure on the medallion to hold it in place until the mud has set.
