I have a 5hp air compressor I need to run on a generator. The compressor draws about 15 amps. It was connected to a generator with a 50 amp male plug. That generator was moved to another location that needed the extra power for HVAC intermittently. the generator I planned to use instead is a continuous 5500 watt but only has a L14-30 receptacle for 220/240 volt service. now to the problem/question. I was changing the 50 amp male plug to a 30 amp L14-30 and discovered that there are only three wires to the compressor 2 lines and a ground/green wire . The green wire was connected to the ground terminal on the 50 amp male plug and the 4th neutral prong was left off the plug. I checked the continuity between ground and neutral on the L14 and they did not show continuity. Will not having a neutral hurt either the compressor or generator? Could I just jump the neutral to ground on the plug or in other words connect ground to both neutral and ground? I know gens etc can be picky about this type of thing. What can I do to run this compressor on that generator (assuming then generator would start the motor)? Thanks in advance for any help to new member

I have a 15 amp GFI outlet in the garage. It serve to protect an outlet outside and apparently a number of outlets in the house in both the living room and the basement. All the lights and tv's go out in those rooms whenever this GFI trips as a result of moisture associated with the outdoor outlet. We also have a refrigerator in the garage which is plugged in to the GFI outlet. A couple of questions: (1) can I put a second GFI outlet in the garage coming off the existing GFI outlet to separately control the refrigerator, and (2) how do I wire the existing GFI outlet so that it only protects the outside outlet but none of the other outlets connected to it inside the house?
