Electrically savvy folks, does the bottom wire look corroded to you? (slrpnk.net)

I’m in an apt. and the power has been shutting off lately. It doesn’t trip any of the breakers in the breaker box inside the apt. but it does trip the master breaker on the box outside. Thought it was an oven issue but it still happens with the oven breaker off.

Visual inspection of the breaker box outside shows one of the wires looks a bit corroded. Wires to/from the rest of the units are a nice copper color. Is that a red flag?

Landlord is dragging their feet and telling us to talk to the electric company, and electric company is saying to call a licensed electrician, so I’m just trying to understand the issue so hopefully the landlord will listen to me.

Excellent, I will grab a couple that will be especially helpful for the kitchen where we occasionally accidentally run the microwave at the same time as the kettle.

I’ll still prod the landlord to have someone come look at the power main issue.

    That’s great. And glad youre pressing landlord. They’re very likely obligated to cover expenses related to this, but I understand landlords are shitheads and a PITA.

    Just to be clear, re: MW+kettle example, typical GFCI won’t prevent that overload. Circuit breaker should trip. There is a similar component that does both (AFCI) but it’s more expensive and shouldn’t be needed if your breaker is functioning correctly. Adding GFCI is usually inexpensive enough to justify but is only meant to protect against faults, not overloads.
