Thank you for all the great interest and the comments on this topic. Here are some more details on this project: 1. 200 A fused Zinsco Main Switch at the service entrance (45 years old) 2. Inside the house Square D Split-bus "Main" panel with two 100 “Mains” fed by 1/0 wire from the outside 200A Main fused switch 3. Next to it Murray 100/125A Sub-panel (Newer, some damage) 4. Outside Zinsco 125A Sub-panel 5. In the pool room 125A Sub-panel 6. In the garage Murray 125 A Sub-panel (newer, looks OK)
The utility is SDG&E, so no line or load side taps are usually allowed. On another project, we have previously replaced a similar type fused main switch with a Eaton Solar Ready Loadcenter with 225A rated buss and 200A main breaker in order to be able to backfeed max. 70 A of PV. I am leaning towards doing the same on this one.... In this case, I will recommend the customer to upgrade/replace the old Square D split bus panel and items 3 & 4. as well. Any other suggestions are welcome. Happy Holidays!
