During that time 1992 the electric tape was very sticky wrap around on receptacles and light switches that the load of the lights was using standard tungsten filaments, long before LED’s or CFL’s was use, back in those days the house was constructed in the late 1970’s or early 1980’s in Sierra Madre area of Los Angeles California. Like I said we use ACME metering device that can read off the main meter that can read current and voltage and give us give us true power and apparent power readings. At that time for myself I do not know the tape was a 3M product but more than likely it was a offbrand electrical tape that can conduct small currents that can not be enough to trip the circuit breaker but enough for the watt hourmeter to read 8 Amps of current at 120/240 voltage of wattage 24/7 a day. The house is a 3 bedroom w/ Central HAC with a swimming pool and it had roughly 25 circuits in that panel active. We dealt with some 80 receptacles and some 20 light switches whether or not it was Singlepole or three way lighting switches that we had to deal with to remove the electrical tape off those devices. Like I said the electrical tape could be a offbrand product that it was produced South of the border or some where overseas in a Asian country that don’t follow production procedures of the electrical tape material.
