[Amps] 220V wiring: Was Question about safety ground connection

[Colin Lamb]

Ian asked:

"You mean the USA is building homes without glitch resistors?"

Response:

Not exactly.  It seems rather circuitous to use the heaviest house wire you can find to the amp, then use a glitch resistor in the high voltage supply and a surge resistor in the filament line.  A simpler approach is to use the smallest wiring possible.  That will reduce the surge filament current automatically and also act as a glitch resistor when there is an arc in the high voltage.  This would allow the manufacturer of amplifers to save something like $1.73 cents in additional material.

For those who have their house already wired, an extension cord of 50 feet of #16 added between the amp and the wall outlet should do the job.  Coil it up and put a rug over it and Fido will have a nice place to curl up.  Cats already know that the tops of Johnson Valients are a good place to curl up.

To prevent homeowners from replacing circuit breakers with ones of larger value, the new code will require wiring to have fusible links spread throughout the house, behind locked panels.  If any of the fusible links fail, it will require the homeowner to call a licensed electrician, who will then have to report the homeowner so that the appropriate fine may be assessed for exceeding the the current limit in a residential zone.
