First - I'm not asking for DIY help. I know better than mess with power (I'm an IT guy and I know my limits)!

At work, we have some 3 phase 208v power plugs that I'd like to use. However, the receptacles on these outlets are NEMA 14-30R. The computer equipment that I need to plug into these outlets are NEMA L21-20P. Can an electrician simply change the outlets? Or is these something physically different about the power?

Thanks,
Tim
