I’m thinking of relocating my gen 2 hpwc to a different residence. Can my electrician simply change current setup over to a nema 1450?
It depend if the Neutral was installed. If there is no Neutral, may be just replace the Powerwall with a connection box to protect the wires. To have a legal NEMA 14 50 require adding a Neutral, and may be a new 50 A circuit breaker. Adding a new wire in a conduit is not easy, unless it is very short with not too many curves. So it would be simpler to put connection box and put back a new Powerwall when needed.
If it doesn't have a neutral (they both need ground) you could put in a 6-50 instead. The 6-50 does not require a neutral wire.
Also, depending on your current braker, make sure to adjust the settings inside HPWC to match the new setup (in case it is different amperage).
@bmms8 You're asking if you can put in a 14-50, but have never once mentioned how many amps your circuit is for you wall connector, so it's impossible for any of us to answer that question yet. The answer is certainly "yes" for the more generic question of "Can I replace my wall connector with an outlet?" Always. But these questions of what kind of wire and circuit breaker will have to determine which kind of outlet. So more information please? What's the breaker and wire gauge/type in this?
Thanks for the feedback guys! It’s a 60 amp breaker with 6 gauge wiring. if no neutral I’ll do the 6-50. It was a lot of labor as the panel is 150 ft from hpwc
