I can't agree with that. Every industrial facility and power plant I've worked at has a battery of UPS systems for the sole purpose of maintaining a steady power source to electronic devices. We do not provide that level of protection for any of the motors. The motor circuits simply trip out on under frequency, or over current.

In my home, I have spare aquastat relays for my boiler, spare 110>12V transformers, spare 12V zone valve motors, ect. I do because I have to replace them frequently.

If you know something I am not considering, I'd love to hear it.
