Does anyone know off the top of their heads if there is any code preventing primary sheilded feeders from being placed in PVC schedule 40 PVC. Seems like 80 is the minumum but cant find the article.
Also, I have a situation where a customer has fed from an S&C switch to a fire pump transformer, then jumped out of the fire pump transformer to the main service transformer . The fire pump xfmr is 300kVA. The main xfmr is 1500KVA. The wire is sized for 1500kVA and fed to accomodate the 1500kVA. Basically the 300KVA is used as a feed through. I feel like it is sound from a design standpoint but i don't like it. I'm more worried about the firepump requirements as for being independent feeder.
