Updating 2 prong electrical outlets Free anonymous chatting to pornstars
A common question I get about older homes is whether two-prong outlets can safely be changed over to three-prong outlets.
Most home buyers today don’t want to be stuck with two-prong outlets throughout the house.
With the circuit energized, touch one end of the tester to the hot wire, which should go to the smaller slot on the outlet, and one end of the tester to the electrical box (see photo below left). Now all you need to do is attach a bare copper wire to the box, and use this as the ground wire for a three prong outlet (see photo below right).
If you perform the test with a pig-tail tester and the light doesn’t light up when you touch the hot wire to the box, the box is not grounded (or you’re not touching a hot wire).
In this case, you could run a ground wire back to the panel, or you could replace your two-prong outlet with a GFCI outlet.
The third prong on an outlet is commonly referred to as ‘the ground’, and it provides an alternate path for electricity that may stray from an appliance or product.This is an important safety feature that has been required since about 1962.
