We are buying a 1950's ranch in MA that has a 2-prong electrical system, 100 Amps, and isn't grounded.
We'd like to switch the whole 1900 sq ft house over to 3prong outlets (grounded) and probably new wiring.
Anyone have this done or know what an approximate estimate may be? We want to have a ballpark figure when we get estimates from electricians.
Thanks in advance!
This one pretty much requires an onsite inspection. There are too many factors that could affect the price. Thing such as access from a basement below or an attic above. It could be that you don't need rewiring. It is possible that grounds are in the boxes and just need to be utilized properly on 3 prong receptacles.
