    Default Electrical Wiring for onboard Generator

    Our rescue truck has a factory installed generator as well as two outlets in two different compartments. The builder used a 3 prong locking receptacle and as a result we have to keep up with special adapters to connect regular extension cords. I am looking to replace the outlet with a standard commercial 120v outlet, but I wanted to make sure that I am not overlooking any NFPA spec that says the outlet must be of the locking type.

    Thanks.

    "Twist Locks" are common in the fire service because they are not likely to come out accidentally. Also, many of them can be provided with water resistant boots, lessening the chances of problems due to them getting wet. (We do have this funny habit of getting stuff wet.)

    On the other hand, when I was in the Navy, ships used what was referred to as SNR plugs and receptacles, which wouldn't come out either. But now when I go aboard Navy ships, I see that everything is regular house plugs and receptacles. What is this man's Navy coming to?!!

    Yes, I completely understand their purpose but when you use an adapter that converts twist lock to a standard 3 prong then you defeat the purpose. For reasons I won't get into they won't let me retrofit the extension cords with a twist lock end. Thus my thought was instead of having to keep up with an adapter why not just eliminate it.

    Question Twist lock plugs

    What's the rating on the circuit breaker for that circuit? If it's 20 amp. I think you can only get twist lock style recepticles. 3 prong house hold style recepticles are normally 15 amp rated. You should replace circuit breaker with 15 amp if you convert the outlets.

    There are many 20amp 3 prong house hold style recepticles . In my area, 20amp recepticles are required in household kitchens.

    NFPA does not have a standard on locking outlets........yet.
