I do not want to back feed my House Panel with my Generator. through the Dryer hookup....but I would still like to use my water heater so I would like to convert the water heater to use a NEMA TWIST LOCK....that way when the power is out I can connnect the water heater directly to my generator...

my problem is the Generator has a L14-30R receptical whitch has 2 hots a ground and a nuetral....

However my Water heater only has 2 hots and a ground.... what is the proper wireing set up to get the water heater to connect to the I build a 4 lug twist lock and use no nuetral? or do I skip the ground?

thanks in advance

Watch this intro

A transfer switch is the best and safest method to isolate your generator from the power company grid.

Make sure it is properly installed. With the toggle switches you can shut off the WH and run lights, furnace, sump pump, refrigeratro, freezer, etc. Then shut everything else off and heat your water.

Dartagansmith - hi, TShea1's advice is the best to follow - you can get a smaller transfer switch and have it wired only for the water heater. The whole reason for the switch is to prevent a deadly backfeed that leaves your house and could severely injure/kill the linesman trying to restore power after an outage. Up in VA after Hurricane Isabel, we had two linesmen - both from other states - killed because of backfeeds.

I don't know for sure but it sounds like your generator connector is able to put out multi-phased 240VAC. Your water heater only needs single-phased 240VAC. Again, a qualified electrician can easily hook up a transfer switch just for the water heater to solve your dilemma. Regards! Jim D/West Point, VA
