Safe to use twist-lock plugs with regular home electrical? (USA)? (alien.top)

I recently got some free gear* from a business that was vacating their space, including a hefty UPS and some PDUs that use 3 prong twist-lock plugs. I'm not familiar with this type of plug, and I'm wondering if I can just use an adapter to power it with my regular outlets. The cables look beefy and I don't doubt they could draw some high amps.

EDIT: Okay, looks like there are multiple types of "twist lock" plugs in the NEMA standard. I'll have to go into the basement and figure out which one I'm looking at, and probably just look up the UPS spec sheet as well.

Depends on the unit- there is a twist lock 20 amp 120v NEMA plug, but that's very unlikely to be what's going on here. You probably need a 30 amp outlet at 240 volts, but be aware of what voltage this specific UPS runs on. If it's 208, you may not be able to use it at all. If it's 240, you can get an outlet installed to power it.
