Undergound Service Upgrade

[Ken9876]

I have a U200 SWUG meter pan feeding a 100 panel now, can I just replace the panel with a 200 amp, or do I need to call the POCO?

Usually the 100 amp panels were fed with a 100 amp meter base. If you are going to change to 200 you need a 200 amp base and proper size conductors.

This is a 200 amp meter base, I've never upgraded an undergound service. Which is why I'm asking, not sure if the POCO underground needs to be changed it looks plenty big enough. I would change the conductors between the base and the panel of course.

Local rules vary.


Contact your POCO.

I've always left the 200A meter pan in place. If it's in really bad condition then it's a different story. Otherwise there's really no reason to change it.

Is the load changing? If so the POCO needs to know. Most places you have to call them to have a meter removed legally anyway.

I missed the fact that it is underground. Generally underground services, at least around here, terminate in a 200 amp base. I bet you are probably not adding that much load but you definitely need to contact the poco. Many of them will have run 200 amp wire for a 200 amp base.

I always call poco since an inspection is needed anyway.

Thanks for the info
