I have a 30A breaker going to a 50A spa panel, going into a project box, going out to a 120V receptacle and an Auber PID. 5500W element installed in keggle using Kal's weldless method. How do I go about thoroughly testing the wiring/grounding/installation? I have a electric meter and a receptacle tester.
I am not sure you should test it. 5500 watts/120 volts = 45.8 amps. Is your spa panel 220/240 volts? If you use a 240v rated 5500 watt element, running it on 110/120 the heat output wil be less then half.
Sorry I wasn't clear. The PID/SSR is run off 240v, not 120V. I have split the circuits after coming into the project box. 2 hot legs to the SSR/PID/CAMCO circuit, one hot leg going to the 120V receptacle.
