2 prong to grounded outlet question
We are purchasing a house built in the 1940's with 2 prong outlets throughout. As part of the remodel, we are upgrading the service to 200A circuit. The electrician also quoted me a $20 charge to change out each 2 prong outlet to a grounded 3-prong one. I'm wondering how difficult this would be for me to do. I have done basic things like installing ceiling light fixtures.
Help/advice is greatly appreciated.
