I will describe two issues and the likely culprits
One: You have 240 volts hot to hot and 120 l=hot to neutral (eitehr side) no load but when you turn things one. especially Heave eaters like the water heater or my lady's hair dryer or the nicrowave or one A/C the voltage on that leg goes DOWN and the other UP.. (Note a volt or two is not a problem 10 volts is) Open or high resistance NEUTRAL.
Your problem.. one leg stays at 120 and the other drops like a rock under load
Proglem high resistance that leg or way too much load
True story (Mine) When my rig was new sometimes one A/C worked, sometimes the other both or neither.. So i started tribble hunting (I'm a certified electronics tech) First stop was the breaker box (power distribution panel) also as it turns out, the last stop.
one of the screws holding the wires took over 3 full turns before I was happy. oh, yes once all (And I tightened every screw that turned) (UNPLUG FIRST) everything worked fine.
Other locations: The plug (Shore cord) Outlet (Shore cord) Inlet (RV) I had a loose screw on the inlet too.
Fellow RVer plugged his brand new sticker still in window 5er in and NO POWER.
Grabbed ye old multi meter (did not need it) and started diagnosis.. Shore cord outlet (The end that plugs into RV is called the outlet The "Socket" on the RV is actually an INLET (Plug) Fell off in my hand
The thing has 9 screws, 3 that hold the shell together and 6 that clamp the wires and cable. not one of those six had been tightened.
I've have loved to be there when the owner returned to the dealer for a "Chat".
Oh. I told him how much to bill (150/hr minimum 1 hr minimum) Though I did not bill (Fellow RVer after all)
