[Amps] Working on my Darwin award

[Carl]

That is the first panel hole I made on the HB 3CX1000A7 1500W 2M amp almost 
30 years ago and duplicated later on the 8877 222, and GL-51064 432 MHz 
amps.

Breakers, 240V contactors, and step start at those power levels are 
mandatory in HB IMO. Also reasonably idiot proof for my senile citizen 
years....
