In HF power amplifiers, I have found a good general rule of
thumb is this:
At 30 MHz is the clean braid from RG-8 cable has about the
same current carrying capacity as #14 or 16 tinned solid
buss wire.

I've replaced quite a few coax cables from the tank coil to the relay on a number of well known amps.
The braid would get hot, the dielectric melt right where it went into the shield, and then short.

It was easy to fix and I never saw it damage anything else, except for a few DXers dispostions. <G>
