The home inspector occasionally finds within an electrical panel, a condition known as double-lugging.
Double-lugging or double tapping is where two electrical wires are connected to a single screw or lug – usually done by a wannabe electrician.
The amateur electrician does this because they didn’t want to buy another circuit breaker or there was no more space for an additional circuit breaker.
When two wires are secured under one lug, one of the wires might not be completely secured (loose), especially when two different wire sizes are used.
If a wire becomes loose and pulls out, it can arc and cause a spark or create high electrical resistance where the wiring over-heats and starts an electrical fire.
