I have a curious situation I could use some ideas on. I recently installed a new 200A meter combo panel (square D 2040M200S) for a homeowner who still has a 60A fused service from the 1940’s. It was/is a parallel install where I temporarily backfed the new panel through a 60A breaker while the homeowner arranged the cutover with the poco. I hadn’t heard from him in several weeks and now he tells me the 60A service is working fine and doesn’t want to go through with the service upgrade.
The problem I have with that plan is the 2040M200S I put in does not have a bonding screw or other method to isolate the neutral and to do so would void warranty/UL, etc. Since I’m coming off the fuse box which is essentially a main disconnect the new panel is of course a sub. At this point he’s not going to pay for any additional work so I need some sort of reasonable way to resolve this that is still save. I may be able to change out the guts with a main lug. Other options like ‘walk away’ or ‘repo the panel’ or ‘hot bypass the fuse box’ don’t sound reasonable to me. Anyone have any tricks that might work in this scenario?
Thanks, Dave
