Troubleshoot water heater breaker keeps tripping. Install Polaris tap for air handler. Existing tap was a blue wire nut. I recommend getting a whole home inspection. Replaced disconnect for water heater and installed new whip from disconnect to water heater. Replace breaker for water heater. Additional concerns were brought up to the home owner regarding original installation of water heater circuit. Homeowner is aware that circuit should be run in conduit. Romex is not allowed to be sleeved in wet locations. Everything tested and working properly.
