The 1500 watt amp

[JonKG6VDW]

Wow Wayne... who knew you had so much in you.  The world is a better place
with you in it.  You should run for President.  No, nice people don't
deserve that much punishment.

Watching this from afar, I notice the irony - US has 1500W limit but not
enough (120v) mains power to use it, whilst the UK has loads of mains
power (240v at 13A) but only a 400W limit.

> The KPA500 can be run from any decent 120VAC mains outlet as long as there aren't too many other loads on it. But going above that power level forces the Ham to have 240 VAC in the shack, something many of us do not normally plan for. That can be a very expensive addition to the cost of the amp, especially if the mains panel is not expandable as needed.

Running 240 to the shack, while not a trivial task, is not "undoable".
I am doing so right now...  I am putting in a sub-panel to deliver the
power from the service, and am running separate circuits for 8 x 20Amp
120 V receptacles, 2 x 15 Amp 240 V receptacles, and 2 x 20 Amp 240 V re
ceptacles.  All using twisted pair wirin g of at least 2 wire gauges
above code for power level and steel conduit for shielding from service
to sub, and sub to 6 gang metal back box...

Have a master electrician who will inspect and sign off on the work to
satisfy the insurance guys...

Every house I know of in the US has a split phase 120/240 line in, usually
at a minimum of 60 Amps and typically 200 Amps.

You are correct in that the 240 V only goes to specific items, such as the
water pump, stove, HW heater, clothes dryer etc.
One has to purposely wire the "radio-room" for 240V.

I have 400 Amp service, mainly to force the local power company to use
larger feeders to my distribution panel.

I am all electric (if you don't count the 5 chords of wood we cut and burn
each year) and even on an electric co-op out here in the "sticks", we're
paying under 14¢ per kW-hr.
It'll stay there if we can keep the coal industry afloat.

What an excellent idea...  Wonder what that would cost me to get my
power provider to do?

I'd do pretty much anything to get new/larger feeder lines into my house...
