Single phase 230v 60hz 5kw in US with two 120v legs
This question is surely answered somewheres around here, but dang if I can find it, so I am asking for some help from the esteemed and highly qualified panel:
The appliance is a 1Ph, 230v, 60hz, 5kw load, GSHP with g,N,L. There is a snippet of the wiring diagram below...I want to connect it to my electric power in the US: single phase, 60hz, two 120v legs. One way is: connect one 120v leg to L, the other 120v leg to N, white to ground. Is that good enough?

No. You have two hots, 240 volts between them.
Connect one hot to "N", one hot to "L", and a ground wire (green or bare) to the ground. White can not be used as a ground. You will need a 30 amp circuit for this appliance and #10 wire.

'Bout the Line and Load, Hot, Neutral and Ground: this connection as you described was not what I might have done. I would have messed up the neutral and ground, So, load ground will go to line ground.
I got it! Thanks!

A followup: What would you do about the neutral wire. Would you just not run it to the appliance.
Pardon my ignorance: I am not sure what the difference is in using the neutral vs the ground since both are bonded in the distribution panel (in this case)

The ground is not a current-carrying conductor. It exists to carry power safely to ground if something malfunctions. It can be thought of as equivalent to an emergency overflow pipe that dumps out directly onto (into) the ground, in a plumbing system.
Neutral and ground are never connected together on the load side of the service entrance.
