I have pool heat pump plugged to 30A outlet, with 10#

my questions :

  1. following instructions on the plate, is it ok to leave this pump plugged to this 30A outlet (connected to 30A breaker) I mean is it safe or I must use 20A circuit, breaker 20A + 12# wire till the pump ( disctance 37' ) I don't have enoug space on my panel, so can I remove this 30A breaker and replace it with 20A ? (wiring as well )

  2. I heard that if the heater is hard wired is better than outlet because of wattage loss, is it the only reason or is it safer also ?

Thanks

  • "10#" # is not a descriptor for wire that i am familiar with. Do you mean AWG ( gauge ) en.wikipedia.org/wiki/American_wire_gauge – Alaska Man Jul 10 at 18:38

    Number ten (#10) as opposed to ten pound (10#). – isherwood Jul 10 at 19:03

The max rating is 25a so replacing the 30 amp breaker with a 20 will probably work. Most jurisdictions don’t allow a plug for a disconnect it would be proper to have a standard 30 or 60 amp rated disconnect , if it Tripp’s the 20 amp on start up you can use a larger breaker but because the MFG states max 25 that’s the max. You can always use larger wire so that is fine.

  • "most jurisdictions won't allow a plug for a disconnect" Is that because it could just be plugged back in without the maintenance person knowing it? – JACK Jul 10 at 19:05
  • For a permanent install a disconnect is usually required corded devices are considered portable. – Ed Beal Jul 10 at 20:12
  • Yeah, the limitation is on using flexible cords to connect permanent equipment, not in using a socket as a DC. Too use a cord it has to qualify for one of the excuses in 400.6-8. – Harper - Reinstate Monica Jul 10 at 22:19
