Wiring to sump pump

I have a direct dedicated circuit to a hard to get to sump pump in a crawl space .I have it on a regular outlet with gfci breaker.Can I have it directly wired to junction box coming off the panel to it to avoid false tripping off moisture in the outlet ,Would this be best, to avoid moisture in outlet?.Its a pain to get to if I ever have to repair it again an it's only 4 or 5 ft from outside vent.
It's on a 20 amp gfci breaker an 12/2 to receptacle.
Thanks

Code requires a sump pump to be on a GFI circuit.
Cutting the plug off and hardwiring into a junction box is not approved.

It would take a lot of moisture in the air to affect a plug and receptacle.



I can't make an unapproved method recommendation but....
Personally..... for a sump pump.... I usually supply a single receptacle on a dedicated circuit.

Ok i thought ,like disposals, these could be direct wired .
Would using a outlet box like those used for outside outlets with clear plastic cover be a better option than a open receptacle regarding any possible moisture tripping the gfci ?

Actually.... an open receptacle will stay dryer unless you have water dripping from above.

Those in-use covers keep the moisture in longer.

Use a GFCI receptacle at the entrance to the crawl space and run a regular receptacle at the pump off the load side of that receptacle. Plug a night light into the GFCI receptacle at the entrance to give a clear indication you have power.

Those disposals don't come with a cord. The cord if used is added at installation. The pump come with a cord. Cutting off the plug voids its UL rating and therefore violates code.

You can try it. Of course it could be the pump.

In your setting.... if you are having tripping issues..... it's most likely the pump itself.

I think your concern is baseless unless it is face up and the crawlspace floods.

Some states have exemptions to the NEC and you are not required to use a GFCI for a sump pump in those states. Oregon is one such state.

So ask your local electrical inspector, get it straight from the "horse".
