? For largish tetrode amps., I use a standard 50A 3-contact electric
dryer outlet, wired with #4 Cu. The neutral is #8. Amplifiers are wired
so that neutral connects to the front panel whenever the amp. is plugged
in. Thus, if a L1 or L2 short occurs, the mains'-breakers trip and the
front panel can not become fatally hot. .
