Don't do it.

In reply to Older house rewiring by Peter Walter on January 9th, 2001 09:04 PM [Go to top of thread]

I am a licensed elctrician my advice is to leave the old wires alone. Most electrical devices only have 2 wire connections anyway. Replace old receptacles with new 2 wire ones if only 2 wires are available (ungrounded). The wires (sheathed electrical cable or NM cable) will be securely stapled & can not be removed without taking the walls down, don' try pulling on them . If your home has conduit or armored cable (flex with wire already in it) you can try replacing the 2 wire receptacles with 3 wire self grounding type, these receptacles have a special clip on one screw to carry the ground. Do one first then test with a plug in tester.If your home uses fuses make sure they are the correct size 15 amp for #14 wire & 20 amp for #12 wire, when in doubt use 15 amp fuses for safety. Rewire when the opportunity presents itself like bathroom or kitchen remodeling. Also consider installing new wiring for entertainment center, computer or other things that need separate circuits or a ground for their proper operation or for the operation of surge protectors.
