This is some major myth. Crack open your insurance policy — it’s not going to say “UL listed appliances only” or anything like that. Insurance also covers mistakes.

But you should get a good power supply anyway because the hassle is not worth it.

My bad on perpetuating the myth regarding homeowner’s insurance and UL listing, I appreciate the correction.

You’d need to read what the policy has to say about uninspected electrical work performed by or at the direction of the homeowner. If you use a hardwired power supply, non-UL/cUL equipment won’t pass an inspection [0]. You can bypass the inspection by using a cord and plug 120V rectifier which wouldn’t need to be UL listed since it wouldn’t need an inspection.

[0] NEC Section 110.3(c): https://up.codes/s/examination-identification-installation-u...

> 110.3 (C) Listing Product testing, evaluation, and listing (product certification) shall be performed by recognized qualified electrical testing laboratories and shall be in accordance with applicable product standards recognized as achieving equivalent and effective safety for equipment installed [1] to comply with this Code.

[1] ‘Equipment installed’ means hardwired.

You might need permits, inspections, and to worry about code if you’re permanently wiring this into your house electrical system. If you’re doing that, you’re probably well beyond asking about Christmas lights on HN.

ESA in Ontario, for example, allows you to do your own electrical work. Self-notification, I’m sure, is a CYA formality by them.

Ah, good point. I was picturing this setup as hardwired.
