Power Surge Protector 220V-60A

[Strider17]

All:

I need to build/buy a power surge protector for a 220V-60A
Double Oven. Or, Plan B, something inside the oven to protect the control/display circuit boards at a lower
voltage/current rating.


Background:

My elderly mother lives alone in rural area prone to
power failures. The last one wiped out her washing
machine and double oven, both with digital displays/controls (expensive!) I wish I could
play a tape of the phone calls to the power company,
and appliance mfr. Any help would be appreciated...
Please keep it simple, I am an ME...Thanks...

Your problem is more likely lightning induced surges. Power failures don't generally burn out equipment. There are surge arresters available from your local wholesaler that may be installed in the main panel. You may want to consider installing a surge arrester intended for a submersible pump on the oven circuit.

Lightning may be a possibility but there are areas of the left coast of the U.S. where lightning incidents are minimal. In a rural situation, you could have a fault (short circuit) hang on to one of the phases without detection and the homes connected to the other phases would see high voltage.

Ovens are normally connected to 240 V but their controls are connected to 120 V. The washing machine would be connected to 120 V also. Was it just the oven controls that went or the heating elements too?

No blinking lights?

Did you get any response from the power company?

You might want to look up devices called TVSS: Transient Voltage Surge Suppressors. Come in a variety of different sizes, voltages packages etc.

First, her homeowner's insurance may cover this. I'd request that the power company come out and check their grounds and neutral wiring at the service. If their system is at fault, they will pay for the replacement. But the problem could be on your side of the meter, then it is your responsibility to troubleshoot and repair, if necessary. I'd suggest getting a reputable electrician there to check things out. It will be expensive, but you'll sleep better.

Then have the electrician to install a UL-listed TVSS at the service entrance.

All:

Thanks for your replies. Further info:

The washing machine has been replaced with analog type.
The damaged oven heating elements were OK, no flashing
lights, and there was 120V power to the circuit
boards.
There was no apparent lightning at the time...there
much wind which blew over many trees/power lines.
The oven was replaced with another with digital
contols/display (against my advice).
The homeowners insurance co. tied with the power
company for laughs at me...
I will have the power company check their ground
and neutral.
I will investigate TVSS's

One other question: Could a splice a standard 120V
surge protector inside the oven in series with
the 120V supply to the new oven circuit boards?

Thanks again...
