Hi all,
I have a wall-mounted receptacle Nema 6-30R in a 30A circuit (30A breaker and 10awg). In the facility, we have two cord & plug devices. The first one has a plug Nema 6-30P, so we can connect it directly to the receptacle in the wall. The second one has a plug 6-20P. As I understand the NEC, article 406.8 "noninterchangeability" does not allow to connect the 20A plug to the 30A receptacle.
However, a fellow told me that we could use an extension cord adapter if it is built (cable, blades, etc.) to stand the maximum current rating of the circuit (30A); this will be like a short extension cord with two ends, one end will be 6-30P and the other 6-20R. What are your thoughts on that? Below is a link with an adapter like the one described.
is this a code violation? How can this be sold?
Thank you so much!
