GFCI Required?

[SeaBee]

We have a couple of carports installed for a rescue vehicle (ambulance) and a fire engine. I need to install (2) cord reels for these vehicles for a ship to shore power condition.. The ambulance has a GFCI in the power compartment. In the past there has been a GFCI installed on the circuit for the ambulance and we had nuisance tripping. So is there a way way to avoid installing the GFCI on these circuits by installing a twist lock body connector on the end of the cord reel?

If the cord reels are installed in a place where GFCI protections is required there's no way around it regardless of what type of body connector you put on the end of the cord.

I would think I would want GFCI even if it wasn't required !
Metal vehicle isolated from ground on rubber tires.. nice rainy day and one grabs the door handle...

It's important to remember that GFCI protection is typically dictated by the location of the receptacle outlet and not by what might be connected to that outlet.

I guess the EMTs and FD don’t need protection. They all know CPR.

Find the faults. They are not nuisance trips if you have replaced the GFCIs already.

You bring up a good point.

Has anyone figured out if 30 and 50a RV Pedestals are now required to have GFI protected outlets?

Trading nuisance-tripping for nuisance ripping-the-plug-off-the-cord .

(And generally speaking, cascading GFCIs should not cause nuisance-tripping. Could be that the shore-power input does have more leakage than a standard GFCI will pass.)

 

[tom baker]

If you had nuisance tripping then the GFCI is doing its job. You don't know if the leakage is 5 mA or 50. Does the GFCI in the ambulance ever trip? If not then the ground fault is upstream of that ambulance GFCI.

Last I knew the jury was still out on this, not sure of code panel in RV section and code panel in GFCI section have hashed it out.
Maybe call Midwest manufacturing or Milbank and see if they have made any changes to there pedestals yet.

Residences and farms where I install RV pedestals, or similar, do not qualify as an RV Park in any way shape or form. They get GFCI protection. I don't see it as an issue.

Are you saying that the manufactured RV pedestals you installed at this farm or residence has a 30 amp SP GFCI breaker or 50 amp DP breaker already installed?

 

[ptonsparky]

No. We supply it with a GFCId feeder or change breakers.
