Help Understanding Electrical Service with two Main Panels

[renobob]

Hello all,

I was hoping you could help me understand my current electrical service. This is underground service. On the first picture here you can see the meter on the left and then a large locked metal box on the right. What is this metal box? It has barrel locks and cannot be opened by me.

Inside the basement are what I believe to be two main panels. They do not feed off each other. Photos:

The reason I ask is because I would like to hire an electrician to replace the Zinsco panel. I like to know everything I can before I hire someone. Are these considered subpanels because of that metal box outside? The reason I ask this is because on the electrical panels the ground and neutral wires are on the same busbar. Is that a problem?

I would suggest you get more than one estimate from electricians. That way you can see if what they tell you matches up. Other than that, we are not allowed to help any further. With that said.....
