Customer needs a new service, but also needs an upgrade from 150A to 200A. He is older and is having trouble coming up with money for the entire change out. He currently has an over head service going to the meter with SEU going to 150A MCB panel inside the house. The SEU cable is trash on the outside. I was thinking about replacing the SEU to a new meter and adding new 200A MCB service disconnect (to meet new codes) and then running SER (aprox 6') into the house and refeed the 150A panel. Then at a later date after he has some more cash on hand change out the 150A panel to 200A to complete the whole service. Does anyone see any issues with this. Wasn't sure since the Service disconnect is 200A MCB feeding a 150A MCB panel. SEU and SER will be rated for 200A. Thanks.
