Default Adding 30amp 240v receptacle for laser in a Operating Room

We have a customer purchasing a portable laser to be used in an OR. Specs call for an L6-30R receptacle. The existing LIM does not have the capacity to supply this load. Mfgr calls for GFI protection. Partner wants to run a 10-3 HG MC cable to the critical power load center and install a Line Guard GFI module at the receptacle location.

They do not make HG 30amp twist locks and will this comply with 517-19 (H)?

This is a small "Surgicenter" facility.

You're feeding a laser... not life critical equipment.

The laser is not being left unattended by staffers.

If it craps out, the good doctor is going to know about it straight off.

So I can't comprehend why the twist-lock receptacle needs a gold plated certification.

Nothing else is destined to be plugged into it.

Surgical lasers have long been connected using receptacles that are not "hospital grade" because no suitable ones existed. The older arc-lamp YAG lasers usually required 50A 3ph and every facility seemed to use a different standard receptacle for them. However, I'd say the code does require that the receptacle be HG listed. Failure of the laser may not kill the patient, but it would be disastrous to have it stop working partway through a surgical procedure. I'd make the owner/engineer answer this question and sign off on a specific part number for it.
