Howdy! The situation: Father has built a 1800sq ft shop, 2 story near house. We are refeeding both the house and the shop from a 320Amp meter base that is to be mounted on an existing private owned pole on the property. Property is about 2 acres, in un-incorporated county. mixed urban-ish. The overhead lines from the power company pole at the street, meet the pole on our property, and then will go down the pole to the 320A can, then two 2"runs,underground, one to the house, one to the shop. I had drilled a hole in the back of the 200A panel, and through the siding for a 2" LB and 2 minutes later Dad said "can't do that". It's holding up everything else. Hard to argue with Dad.

Question: Can I install an LB between the meter can and the main panel of the shop? if so, or if not, why?

Thanks! Sparkeee24
