I have a situation where a 208v/20A PDU (L6-20P) is supposedly hooked to a 208v/30A circuit (L6-30R). Before I order the correct PDU's and whip cords...sanity check...are connectors 'similar' enough that this is possible (with force) or am I going to find we've actually got L6-20R's on the provider side?
Generally, all common electrical plugs and receptacles (straight-blade, twist-lock, IEC, and CEE) are physically sized and keyed differently, so that they can't be connected together, to keep people from connecting loads that require a specific voltage/current to supplies that aren't intended to provide it. While it's not uncommon for someone to replace a plug with "the right kind", this can (in order of badness): 1. start a fire 2. short out and (hopefully) trip a breaker - that's what breakers are for! 3. violate building/electrical codes 4. void your device's warranty As others have mentioned, just "making it work", rather than making it work correctly, can be bad news. People often fancy themselves unlicensed/uncertified electricians. I've seen some of the handiwork from such people, and while their creativity is impressive, having to rip their stuff out and re-do it is not fun. jms
