There’s a home I’m looking to purchase, but all of the outlets, including the kitchen, bathroom, outside, and basement are 2-prong outlets. It was built in 1953. The home does have 100-amp circuit breakers (looks to be the original panel, and it does say “3-wire” on the panel).
Would these outlets need complete re-wiring, or would a GFCI be sufficient? There’s a drastic difference in price between both options, but safety is certainly a concern.
