Re: aluminum in house wiring
I forgot to add that 1 major problem with both aluminum and copper wiring was that Federal Pacific's alledged circuit breakers were acting as circuit melters. Their circuit breaker design would develop arthritis and refuse to trip a few years after they were made. Actually, before silicone lubricants ALL molded case and air circuit breakers had to be exercised at least once per year to prevent this.
I have had instances where I would turn off a Federal Pacific alledged circuit breaker to change a broken receptacle. The customer would then find out that the circuit breaker was allowing 30 amps of load on a 20 amp circuit prior to the receptacle changeout. I would then have to run a second 20 amp circuit to the outlet quad. Evidentally, Federal Pacific circuit breakers worked right when new and would develop arthritis after a few years. Turning the circuit breaker off and then backn on would restore normal operation by unjamming the arthritis.
