[Elecraft] power requirements for a K3S, KPA500, KAT500, P3?

[Dean L]

It's a simple visit to ohms law.
OR
Just grab a "kill a watt" tester and look at your current draw.
With a quick "in the head math" the 15 amp breaker will be fine.

Remember the 30amp supply is at 13.8v not 117v ac the panel breaker is at.

Again

Ohms law.
BTW : glad you asked the question rather than change breaker size.
