There's a socket at the place I contract at and the type is L15-20r.
It's live and available. Per the pdf below, it looks like using either 2 of any of the 3 legs (w,x,y) I would get the 240vac.........maybe?

Can anyone post the corrwct wiring diagram for me? I have both the L15-20p and the L6-30r blanks, just need the correct way to wire them up.
My EVSE is an Openevse and A Juicebox 60A if that means anything.

Thanks

I would expect that if you put a meter on x-y or y-z or x-z you will find 208VAC. The w,x,y is NEMA 14 split phase with neutral. NEMA L15 is 3-phase without neutral. The easiest way to use this socket is to make an adapter cable to whatever plug is on your EVSE. I assume the OpenEVSE has a L6-30 plug which is why you mentioned the receptacle.

The wiring is straight through with the same letters from L15-20p -> L6-30r X->X, Y->Y, G->G. Leave the Z unconnected. I don't think it could be any simpler except that you have to dial down the EVSE to 16A to preserve the 80% rule and not overload the 20A socket and circuit.
 
Thanks miimura. I will make the adpter this week and try it this weekend.

Tony, I should've further clarified that the socket is 20A but my extension cable is 30A with L6-30 ends. My intent is to use my Openevse and turn down the current to 16A.

Thanks
 
Hot to hot and ground to ground and you are good to go.
Yes one hot on the supply will be unconnected.
