Screw Mounted Transformer

[htyner]

I work in the Telecommunications industry as a product manager for a sales firm. I'm looking at a product that I'm wary of. It is a 120V input 12V output tranformer with F Female connector to power house amplifiers for cable services. The one I'm looking at has a mounting tab at the top of the unit. Is there any reason why a unit like this shouldn't be mounted to the receptacle using this tab and screw from the receptacle wall plate. I know its only 12V, but it seems dangerous to have something like this permanently connectected to the power receptacle.



Any thoughts out there?

That's so it doesn't get accidentally unplugged, or for the heavier ones, to give it some added support. Very common on transformers for CATV and alarm systems.

HT, welcome to the forum!

Only one: the original plate screw probably isn't long enough.

It's not an NEC issue, and they're made to be continuously powered.

Plus, it's not really "permanently mounted" in the hard-wired sense.

Welcome to the forums. :grin:


Those transformers are no problem at all and are proven safe over many years of use. Especially since virtually all of the current ones are fused internally and will cut off if shorted/overloaded.

One caveat: Be careful when using them with a metal receptacle cover plate. If the plate slips while plugging/unplugging them you may get a surprise. :grin:
