This is the relay I used for the water heater project first - see my other reviews. I found it a bit noisy under heavy loads (the water heater draws about 18 amps per foot at full load) and was difficult to install. I will replace it with another relay (40 amp instead) and I expect it to work better. I'm sure it will work for another project.
