If your receptacles were fitted a long time back, then you would be glad to know that a new kind of connection method was familiarised on light switches and receptacles prior to that period. This “new” idea was known as stab-lock or speed wire devices. Stab-lock devices have holes in the rear of the device as an alternative of side screws. Some have both screws and holes. When the new homes were originally wired, stab-lock devices made production time fast. Electricians were predictable to squat, strip the wire ends, stab them into the holes, slam the plug into the box and jump to the next one. It was called the Production.
The method followed by Wonpro of fitting switches and plugs is not similar from the methods used in new construction and takes more time, though you will not ever have problems caused by slack connections in the devices. It is advisable that you never use the stab-lock holes.
- Place the single lead wire under one of the two screws on either side of the receptacle.
- Black wire on the gold screw
- White wire on the silver screw
It doesn’t make much of a difference whether it’s the one, upper or lower, as long as black is on gold and white is on silver. This is the precise polarity connection. And this is also the reason behind one of the prongs on your cord is somewhat larger than the other. It averts you from plugging the appliance in with opposite polarity. The circuit will never open now even if you remove the plug from the wires.
When you connect the receptacle, ensure the ground hole is on the bottommost level. As soon as it is on the top, that is a sign that the receptacle is functioned by a light switch. The third hole, or the GROUND, connection is the green screw that is committed to the metal frame of the receptacle.
If you are substituting receptacles, and you happen to see one that has both a black and a red wire on the gold screw side, this is typically a clue that one half the receptacle is at all times live and the other half is monitored by a light switch. In directive to discrete the top half from the bottom half, you have to break the little metal bridge on the GOLD screw side of the plug between the top and bottom.
