What throws me off is the 2 exterior services and house is a single family home.
I found enough issues for the electrician but I had a hard time following the services.
So pics are from exterior to interior.
Here is some info.
2 exterior over head services.
2 panels in basement - one a FPE
1 sub at basement steps.
The cover on the one main was like the one Cameron was discussing on a thread a few days ago, The cover was a bear to try to get back on. Pointed, missing screws, main breaker does not line up with cover.
See pics. Seems like one of the service entry to the conductors at the main lugs go to the sub. I could not follow and why I was asking, why 2 services, maybe house was a double at one time.
I’ve seen two meters and two panels on a single family home several times. I can’t say I have seen two service drops. The houses here that have two meters were done in the past and the second one was just for the hot water heater. At one time they charged a separate rate for hot water.
Two services could be on the house as long as the services are grouped. From the description and interpreting the pictures it looks like there is a service panel for one floor and the service disconnect for the other floor. The other floor would have the panel in the unit.
After studying the single-breaker FPE panel, you got a single phase service and a 3 phase service on the same structure. The 2 panels with multiple breakers are single phase panels. The FPE breaker has 3 poles, commonly used for 3-phase loads. Did you determine what the FPE breaker was feeding? Old homes with central A/C sometimes had 3 phase services for the A/C.

this looks like 1- 1phase and 1- 3 phase service. Not against NEC per se (many meter packs for apts are 3 phase) and you can have 2 services to a building if they are different phases. But certainly not common and you have to ask why? What is the 3 phase load?
