Just noticed that Electrician wired my Equipment closet with 15amp receptacles (NEMA 5-15) on a 20 amp circuit.
This has been "done" for a while now, and I just noticed shopping for rack-mount Power Distribution Units (PDUs). Since I have 20 amp circuits, I was shopping for 20 amp PDUs. But then I noticed they all use NEMA 5-20 plugs, where one of the slots is turned sideways.
- Did the Electrician screw up/try to short us somehow?
- Is this even "to code"? I read somewhere else that 15A receptacles are supposed to support "20A passthrough".
- If I put a 15 amp PDU in the rack, will I get any benefit from the 20 amp circuit? Or, should I make him come back out (yeah, right) and change the plugs?
Not sure what it means to us overall having a 15A plug on a 20A circuit. Can you guys help fill in a complete electrical noob?
