Another- (RENO) we must know other codes.
Local ordnance,via 'sewer commission': Septic ejection/grinder MUST have provisions for generator hook up.
#1 I feel this is a way over step !!!!!!!!!!!!!! Another design issue causing undo expense to the home owner/seller.Thus influencing my Competitive bid.
#2 My plan: 23A-120/250V 1 Phase-4-wire \ Install in the control cabinet: A male L14/30 - on the bottom. then install a WP female wip cord cap.
The end result: cord & plug for disconnect,and a male recept. for the gen set cord.
After that- your problem. No requirement that home owner HAS generator- just that 'provisions ' are made.
Any problems? My local pros think not.

Leland: One may question the use of 'cord' for permanent wiring method, IF I understand that you are connecting the 'normal' supply via cord.
I have to say that sounds like a plan.

Absolutely John.
Permanent wire to a WP box, Then cord and strain relief- perhaps 18"- with a WP female cap- then plugged into a male rec. located in (depending on room-have not seen the controller as of yet-)the bottom- or a suitable WP enclosure.
In and out for a whopping $400.00 +- as opposed to a Grand for a generator interface set up.
Am I far off base?

Well, you could put in a 2 throw disconnect. If they don't install the genny, they never wire the other side. If they do, they already have their MTS. Joe

Le: Joe may have a good idea...Sq D for one has a double throw, 2-3-4 pole, NEMA1 & NEMA3 switch, with full ratings.
May be in same $$ area & a little less time to install.

The application surprises me just a bit.
First, the pumps seem just a tad large for a home. Maybe there's a significant lift or something.
Otherwise ... is it really a requirement for a generator hook-up? Or just a requirement for back-up power?
I ask because I have seen pre-packaged battery systems for such pumps. Set on the floor near the pumps - plug pumps into the unit - plug the unit into house power - done. Might be worth a visit to the plumbing house.

Question. Why the grinder?
Wood work but can't!

Alan, the 'grinder' is a perforated plate in the intake of the pump. A knife spins across this plate. The device is intended to cut up stringy material -think paper towels and sanitary napkins- before it enters the pump.
Pumps have trouble handling stringy materials, as they tend to wrap themselves around the shaft - eventually binding the pump.

All good questions.
1- I have not seen the specs for the pump- Builder over the phone from the book- 120/230 30A-
Hence the 30A twist lock idea.
Priced out the MTS- $400- indoor model. This will not meet the 'insight' requirement.
Reno- Good point. Back up power. I will check.
Please understand, This info is comming from a neurotic builder with no buyer yet. and power is still another 2 weeks away.
But, all the finish is done, so as to 'stage' the dwelling.
Pain in my Butt this guy has become!!!!!! Wants it all temped out to look finished,from a neighbors 20A ckt. (on ext cords) AAARRRGGGGG.
Still, Does my original idea sound reasonable?

I like your original idea. There's no getting away from some use of cords; the pumps and floats have cords, and a portable gennerator will tie in with a cord. There's no way to switch power supplies that is more idiot-proof than having the guy actually move the plug.
