Re-wire 1950's house?
 
I've bought a house built in 1958. All the electrical functions proplerly, but I would like to replace all the outlets with new recepticles that have the ground pin. The old wiring does not have a ground wire going to the recepticles. Can I just replace the old 2-prong recepticles with new ones - without using a ground wire? Or should I be looking to re-wiring the house in the future?
thanks

Have an electrician check the wiring for a ground (some older houses were wire in conduit and the comduit provided the ground) DO NOT replace a two prong outlet with a three prong outlet if it has no ground. You can replace an ungrounded two wire outlet with a GFCI

Thanks. I just saw in an earlier thread that someone recommended that if the metal boxes are grounded, that one could wire the ground of the recepticle to the box. How can I determine if the boxes are grounded?

Use an Ohmmeter to determine the resistance between neutral (the white wire) and the potential ground. If the resistance (ohms) between them is very high, the conduit is not grounded. You could still use GFCI's which are 3 wire outlets, but label them as "ungrounded"
