Are you some type of L530P preacher

A potential customer called me out on a what he saw was an obsession with the L530 Nema designation. (just talked about NEMA plugs a few days ago here)

He noticed that nearly every 2200va UPS has a recommended L530P as the input plug on my website.

As a possible member of the dreaded Plug Police, he reminded me that it was illegal to put a 30amp plug (which is what a L530P is) on a UPS rated for 20amps.  And that no manufacturer recommends this. Even though he called before 8am, I tried to politely reminded him of the tag at the bottom of every listing.

Input plugs changed at no charge

So 1) Its not an obsession, more like a  compulsive preoccupation to have all server rooms use dedicated 30amp outlets for the UPSes.

If I give you a L530P plug on your UPS that means you will need to have a 30amp receptacle to use it.  And a 30amp receptacle is a good thing because: the presence of a 30amp outlet in your server room means your probably have a modern and safe electrical system.  Thats because if you have a 30amp receptacle you specifically asked for it.  Its not ever put in voluntarily by a low bid contractor. And when he put it in it didn't get spliced from another circuit, since there isnt any 30amp 120volt circuits wandering around.  And 30amp outlets typically weren't installed 20 years ago, which means the outlet will be modern and safe and probably up to code.

And 2) Its not illegal... maybe it is in Russia... This isnt Russia?

Ahh, Danny, this isn't Russia. Is this Russia? This isn't Russia, is it?

Amperage designations and related circuit breaker protection is what must be followed.  A 30amp outlet must have #10 wire supplying the receptacle.  A 30amp cord cap (L530P) must have #10 wire on the cord.  True, putting a 30amp cord cap on #12 wire is bad, but if the UPS has a 20amp input circuit breaker on it, it doesn't really matter

Bottomline, I like to put L530s or everything to make it easier.  Your IT rooms are complicated enough.  If everything is 30amp your wont have to keep changing 520s, L520s, and L530s around as you change and upgrade equipment.
