Oh wow that makes lot of sense now. thank you so much for that information.
So, correct me if i am not understanding this correctly but, you would use twist lock connections when power is being pulled over 2 or more phase lines?
Yes to twist-lok. There are a variety of locking connectors for single pole, single phase 2 pole and 3 phase uses, up to 100 amps if memory serves. They also get expensive in the larger amp ratings.
