Troubleshooting electrical issues on model 2910D
« on: March 23, 2024, 07:59:21 pm »
Took the PC out today hooked up to a 50 amp box microwave and AC and the tower outlet on counter below microwave won’t work but when I unhook power from 50 amp box and turn on generator everything works. Why? What am I doing wrong?

Let me first start with what I don't know.  I only have 30amp service in my 2900 so I don't know how yours is wired, if you have the same Automatic Transfer Switch (ATS) , or what invertor & convertor you have.  And if you have a victron multiplus, you can replace below each of my references to invertor, convertor & ATS with "victron" since it is all built into one box.

However, I have a theory.

When on the generator,, which is 120v single phase, the ATS connects the same hot lead to both the A and B sides of the breaker box. Everything works.


When on shore power, which is 2 phase, each 120v, the ATS connects a separate hot lead to the A and B sides of the 120v breaker box. Some things work. Some don't.

Since one side of the breaker box appears to be dead on the power cord it must have one dead phase. Ergo,,, one dead phase in the shore power 50 amp breaker or the source 50amp outlet, a bad power cord (including the chance of a bad plug on either end), bad receptacle plug on outside wall of your PC, OR bad ATS... Or a bad connection between the receptacle and the ATS.

If you have a multimeter for high voltage or a voltage tester (https://www.lowes.com/pd/Kobalt-Non-contact-Analog-Voltage-Tester-50-1000v-Volt/5001927063 which is safer to test with) it would tell you.  I would start testing at the shore power 50amp breaker and work towards your PC breaker box. When the voltage disappears... You found the problem.

Sorry,,,, wish I could narrow it down, but my older PC is wired differently and I have guess at what equipment you have. Maybe a newer PC owner with 50amp can suggest more.

Good luck. And be safe, remember that you are testing a live 240v circuit. Let us know what you discover!
