[Elecraft] Breakers for KPA1500?

[Mark Goldberg]

Let's put this in monetary terms. 100 ft of 12/2 with ground is $56 at Home
Depot. 100 ft of 10/3 with ground is $138.

If you pay an electrician to do the work, the difference won't be 10% of
the bill.

If you do it yourself, following code and getting it signed off by an
electrician and inspected of course so your insurance won't deny coverage,
and you value your time, and there is a chance you may want extra 120 V in
the future, it will save hours of replacing it later.

I would go with the 10/3 with ground, but that's just me.

When you sell your house and the next owner wants to put something else
there, you may get more for the property. For example, the previous owner
of our house installed a 20A RV power outlet. And yes, it came from one
side of a 20A 240V feed with a neutral and ground. That was worth hundreds
more to us.

I would still put in 20A breakers. They protect the wires and if all you
need is 20A for the load, it seems sensible to be more protective. I have
heard of inspectors seeing 20A breakers and AWG10 wire and questioning it,
but it seems you could explain it was done for an extra safety factor, etc.
Breakers are quick to change.

Good luck with whatever you do.
