A customer has a nice DeVilbiss GT5000 generator that he would like to use as a back-up source.
The problem I see is that it has 2 duplex receptacles. One 120 volt and one straight 240 volt(2-wire,3-pole, grounding).
Mine has a 240/120 3-wire 4-pole Twist-lock receptacle to feed a transfer panel or switch.
I don't believe his is designed as a backup source, due to the straight 240 volt configuration.
What do you think?
