Just had my interlock switch and inlet box installed.

When i plug my 30amp cord into the switch it does not twist lock. Should i be concerned about this?

It should twist lock. There are versions that don't but you don't usually see them on a generator.

On either the plug or the socket there should be a number. Something like: L14-30R, or L14-30P. The "L" means locking.

They don't twist very much.

I just found another 30 amp prong plug and it seems there is a slight blockage in the female end of my generator cord causing it not to seat completely in the inlet box enabling me to twist it to lock it. I am going to call the store i got it at.
