It doesn't matter which wire you use as hot and which one is switched when connected to a switch. I have a wiring book that has two different examples. One way white is hot to the switch and the othe

However, if a neutral is in place, and it is bonded to the cabinet, in the rare event that the safety-ground is severed, the cabinet could not possibly become a shock hazard. If it is bonded to the c

Perhaps 120VAC devices were more prevalent then or the tap arrangement was too complex? Recent amps designed for use with either 120VAC or 240VAC do not appear to share this issue. Anyone know what t

As I understand it, arc-fault circuit breakers detect the RF energy from the arc and switch off the circuit. For amateur radio operators, this "improvement" should be even more interesting than GFI b

Depends on the amplifier type and design, but the most significant factor is usually the rf device and how hard it's run. On tube amplifiers, operator adjustment is likely to dominate over everything
