01
The service was bigger than the brand needed. One transformer was the only gap.
The unit has a 400 A service at 480 V, which is more capacity than the brand's standard asks for, and the panel directory showed plenty of spare ways. Everything at 208 V passes through a single step-down transformer sized for the previous use, and reading its rating plate is what pinned that down.
What we recommended
A larger step-down transformer and a new 208 V board, fed from the spare capacity already there. A far smaller job than a new utility service.
