KPA500 external mains switch

You did not specify why you want an external mains switch. I have a 240v
surge protector in my electrical panel, it covers the whole house.

Is anyone in the US using a separate 220v external mains switch on their
KPA500? I'm wondering where these are available. Or is anyone using a 220
v surge protector? Are these available for the NEMA 6-15 plug?

Re: KPA500 external mains switch

I John

I run a remote and have for over 15 years, a lot of that with Amps like the
KPA500. I really don't see a need for a surge protector when you have a
real 'torroid' transformer.

As for 220VAC switch, I use a 12v relay connected to my RemoteQTH server
run by a RPI to turn off the 220AC if I need to. I do do this during the
summer in thunderstorm season, but all winter, I never touch it at all.
The Amps stays powered by 220VAC.

Is there a reason you think you might need one?

If you are worried about lightning, it won't help.

Re: KPA500 external mains switch

Yes, lightning was a concern. Regarding an external mains switch, I read in the manual that circuitry remains ON for remote operation when the amp is off. I don't need the circuitry to be on. However...

...it sounds like I need not worry about either!

Thanks!

Re: KPA500 external mains switch

If lightning is the item of concern, there's bigger fish to fry in that
regard. Lightning protection is an entire other story and a very
specific approach to lightning mitigation.     I use the word
"mitigation" to emphasize the point that all efforts for lightning
protection is an effort to "minimize" the damage. Notice I didn't say
eliminate the damage.   Won't happen.

I told a friend who had asked "how do I protect my equipment from
lightning damage?".   My answer; "put it in the box, seal the box, place
the box under the bed and hope that a lightning strike isn't the cause
for the the house to burn down".    Come to think about it " do houses
burn up, or do they burn down?" Guess it makes no difference.
