For the 3rd time in 3 months I have been having issues with voltage spiking in my 5ver. 230v coming into a 110v appliance or piece of electronics and it will be short lived to say the least. I would think it has to be from the neutral or ground side because I think the breakers would trip if it were going thru the positive. Am I correct on this. At 3 different locations when this is happening. Transfer switch fried once and dealer said this caused a back-feed thru the neutral(fried)wire. Replaced transfer switch and this past weekend did it again. This time claiming microwave(second time) converter, counter top ice maker and not sure yet what else. each time the power pole was checked and voltage was 110-115 each leg and 220-240 across both legs at pedestal. Dealer removed entire 50a cord from outside plug to the transfer switch and found no scars, nicks staples,nails etc in the cord. Any help would be appreciated. Steve A. Dagro

It could be a bad connection on the neutral.
Is this happening at the same location or t different locations?
If different then yes it could be in your rig. If at same location, then it could be the supply.
No, a circuit breaker will not stop a surge.

Hi,
Tighten all the connections in the breaker panel. Check them with an ohm meter when done.
I'd prefer a manual system to a transfer switch.

Three different locations. Also, went thru and tightened each breaker, also neutral and ground and neutral. Do not have generator just the prep. Tech is considering eliminating the transfer switch. 1st one fried, supposedly due to loose neutral. Not sure if that was the case or did the neutral get loose once it fried. Second and third time transfer switch still like new. Steve

+1... that way, you are protected regardless what wire the surge is coming from.

The evidence points to internal problems. A surge protector won't help that.

Three locations? I think it is your neutral some place in your RV that has a bad connection. I would check them all by disconnecting, inspecting, reattach and test.

How do you know it's a voltage spike? If it's a loose connection then it's more likely to be a low voltage problem. Measure the AC voltage to check for bad connections. Do you have a Kil-A-Watt meter? Place in-line with the microwave and measure voltage. Or just use voltmeter.

Every time problem occurs and I check the voltage at receptacle w/multimeter voltage is always 230-238v.
