How to Identify Problems with a FPE Panel or Circuit Breaker
Electrical Question: The house I bought for my in-laws has a Federal Pacific Stab Lok service panel.
- My neighbor said in selling their house which had one, the buyer’s inspector said it was a hazard and MUST be replaced.
- The internet seems to be covered with information saying it is a hazard; I noted these postings are typically from home inspection companies. What is the straight scoop?
This electrical wiring question came from Bob, in Dallas, Texas.
