Question.... may be a dumb one... in a relatively typical Overhead Residential Single Phase 3-Wire Service...
If the exterior disconnect is designated as the Emergency Disconnect only, NOT the Service Disconnect.... could the Emergency Disconnect be rated higher than the Service Disconnect?
For example, could I put in a Nema 3R 200A Main Breaker Panel as the Emergency Disconnect outside....
...and run this on #3 AWG to a 100A Main Breaker Panel inside?
Trying to see if there is a way to do a 100A swap, old for new, with the capacity to be more easily upgraded to 200A than ripping out the entire meter and disconnect.
