Dear Forum Members,

Please Can any body tell the code reference about the 20A American lockable type receptacle required for Data Cabinet/42U Rack.

As a general practice we use lockable type socket for Data cabinet in order to ensure that the Receptacle plug could not be removed mistakenly during maintenance or by the unintentional foot hitting or by any way..

Thanks

There doesn't seem to be any code reference either requiring or prohibiting (in secs 645, 646, 647) using a locking type receptacle, if thats what you're asking.

If you are still doubtful, why not fill in the details a little more about the installation.

Design specification for reasons you mentioned - primarily not as easy to inadvertently come unplugged compared to a straight blade receptacle. Is not a NEC requirement.

The installation is like that, We have 20A ordinary/normal wall receptacle for DATA Rack, from this wall socket outlet the power distribution unit (PDU) of the rack will be connected. My IT/Low current engineer is of the view that it is a common practice to use Lockable type power receptacle.
The installation with ordinary socket is already done on site and now i have to instruct the contractor to replace this ordinary socket with suitable lockable type socket, for all this issue i need a code reference.

And I am pretty sure you will not find any NEC requirement, some other code maybe. Outside of codes, it is just a design decision attempt to increase reliability of the thing.
 
No code requirement for locking plug / receptacles.

Some like it because the IT guys sometimes bang into the plugs and know them out.

You can do it with a twistlock type for regular L5-20 or they make special C13 and C19 connectors that can snap in place to be retained in the receptacle better.
 
It was a best practice at the DC I worked at. Can't tell you how many straight blades were always 1/4 - 1/2 way out. Vibration, cable pulls, equipment being shifted.
