No problem, glad to assist.
1) Obtain a 2 wire lead AC voltage tester or a multi-meter and I will be happy to walk you thru the testing process to confirm if the receptacles are wired properly. Very simple process:)
2) Since the home was built in 1955, grounding was not common. If the home contains any 3 prong receptacles, a high probability that they are boot leg grounded which is a code violation unless they are protected by an upstream GFCI. 3 prong cube testers inserted onto a bootleg grounded receptacle will provide a false indication. Thus the reason to always have a 2 wire lead tester available.
3 prong receptacles were not sold or installed in 1955. They didn't come out until the mid 1960's. So not sure if the home contains 2 or 3 prong receptacles or a mixture of each or if equipment grounds exist or not? If using a 3 prong tester, this suggests that the home has 3 prong receptacles.
If you have any additional questions, just let me know and I’ll be glad to answer them for you.
