bmulvenna@hotmail.com Posted August 12, 2021 Share Posted August 12, 2021 Anyone know what these relays(I think) are for inside of the breaker box? Possibly related to a surge protector? Thanks on advance for any input. https://photos.app.goo.gl/MFLNaRLbnnXyyh798 Mike Mulvenna 2004 Dynasty? Link to comment Share on other sites More sharing options...
Dr4Film Posted August 12, 2021 Share Posted August 12, 2021 One is most likely for your Electric Assist Element in your Hot Water heater. The other is for the Engine Block Heater. These relays are activated using low voltage 12 VDC switches however the relay passes high voltage 120 VAC to the appropriate device. Link to comment Share on other sites More sharing options...
bmulvenna@hotmail.com Posted August 12, 2021 Author Share Posted August 12, 2021 (edited) Thanks. Yes, that is what relays are for. I was looking for any advice as to what they might control.

bmulvenna@hotmail.com Posted August 12, 2021 Author Share Posted August 12, 2021 (edited) Sorry, I did not see them. I don't have a hot water heater. Have an aquahot. Edited August 12, 2021 by bmulvenna@hotmail.com Link to comment Share on other sites More sharing options...
Dr4Film Posted August 12, 2021 Share Posted August 12, 2021 (edited) Mike, That IS your hot water heater even though it also provides heat to your coach. The Aqua-Hot has a 120 VAC Electric Assist Element which is powered through THAT relay in your photo which is activated with a 12 VDC switch which is located adjacent to the Aqua-Hot Diesel Switch. May I strongly suggest that you first find out exactly what Aqua-Hot model is installed in your coach then go to the Aqua-Hot web site below to download your specific model manuals, Owners, Parts, Service, etc. http://www.aquahot.com/library.aspx Edited August 12, 2021 by Dr4Film 2 Link to comment Share on other sites More sharing options...
Dalton07 Posted February 20, 2022 Share Posted February 20, 2022 (edited) This RV breaker box helped my car stay safe when I switch from onshore power to RV power. To wire a breaker box, I need a 50-amp breaker, a circuit breaker box, and several tools, such as a wire stripper, drill and bits, a screwdriver, and a craft knife. First, I choose where to place the breaker box reasonably. Position the breaker box on the wall and secure it with screws. Loosen the fastener securing the breaker box’s dead-front panel. Remove this section and touch the leads with a voltage meter to confirm there is no current. Edited March 1, 2022 by Dalton07 1 Link to comment Share on other sites More sharing options...
