So it’s two apartment house with the original following configuration. The house main switch (one in the middle) is 150A and a 100A is each panel to the left and right of that for each apartmentUm, I'd need a larger picture encompassing all your panels to know what I'm looking at. It looks like you have two meters?
It looks like one meter's output goes into this new "panel" that contains a 100A breaker that presumably services another panel somewhere?? And then you have a 50A breaker there too presumably for the 14-50 receptacle. What is your meter service? 150A? 100A? Is that mini-panel with these two breakers rated for 150A?
I'll also echo the question about grounding.
Which pull cable are you referring to?I don't see a heck of a lot of grounding going on, but maybe that's just the lighting.
Just curious...what's the weird Dune-ish pull cable hanging out of the middle panel?
Based on what I can see in these pictures, I don’t see anything wrong. But there could be things not done right that I can’t see. Does the charger work?So it’s two apartment house with the original following configuration.

He ended up replacing existing sub panel in floor 2 with 4 circuit sub panels. Install dedicated 50 amp circuits with NEMA 50 receptacles. The 100A was originally there and the 50A was the addition of the new panel

Yup the charger works and no issues. I had them file for a permit, so someone from the town will eventually come and check it out . What about grounding, what’s your thoughts on that?Based on what I can see in these pictures, I don’t see anything wrong. But there could be things not done right that I can’t see.

Provided the main box is grounded, the sub panel will be grounded through the conduit. The MC cable going to your 14-50 has a ground wire in it which should be connected to the sub panel box with a grounding lug and screw.Yup the charger works and no issues.

Btw thanks a lot for your feedback! First time electric car buyer and just making sure i don’t fry my house by bad installations lol
I'm guessing that this an old enough install that the conduit is being used as the ground. The neutral in the sub panel is isolated from the box so that's good. I'm guessing the ground wire from the 14-50 is attached to box and not just behind although the conduit also appears to be continuous between the outlet and the sub panel.Yup the charger works and no issues.

In the upper right of the main incoming breaker panel(with the 150A breaker), there's a hole drilled in the faceplate of the panel which looks particularly not-original. The paint is gone all around the hole as well. Generally making your own holes in panels is a significant problem. Making a hole and then sticking a bare wire into it is downright scary.Which pull cable are you referring to?
That looks like an inspection seal. The idea is that you’re not allowed to open that box without the city inspector resealing it.In the upper right of the main incoming breaker panel(with the 150A breaker), there's a hole drilled in the faceplate of the panel which looks particularly not-original.

I'll echo the concern that the new panel that was installed might not have been rated for 150A. I see they've used several adapters to make the holes for wires bigger(!) for the larger gauge wire. I might not be so concerned if it were for the neutral only, but they've done it for the incoming power wires. In any case, the faceplate for the new panel should have a maximum current indicated.
You are right, I'm sure that's what it is! I've never seen one on an interior panel, but since this is likely unfused clear out to the pole I can imagine they'd want to know if someone were screwing around in there. I also see there's one on the lower left of that panel that is a much more clearly a seal.That looks like an inspection seal.

It's because being upstream of the meters, that box would allow access to unmetered electricity. They put a seal there just like the seal tag on the meter base, so they know if someone has tampered with the metering and potentially attempted to steal power.You are right, I'm sure that's what it is!

I'm also a little surprised that the holes were apparently made with a 38 caliber round or 30d nail and a sledgehammer.
I thought of that, but didn't look closely at the meters to see if they had a similar seal. I know my meter box has no seal at all so I could dive in there with some 0 gauge and dramatically reduce my electric billIt's because being upstream of the meters, that box would allow access to unmetered electricity.

Interesting! It's possible it fell off if the meter is pretty old, or your power company just doesn't do it. Usually they're on the meter base door, or there's a metal ring that goes around the meter itself to prevent it from being removed from the meter base jaws.I thought of that, but didn't look closely at the meters to see if they had a similar seal.

Ya, I'm familiar with the seals, I don't think I've had one on there for most/all of my 25 years in this house. Maybe they gave up on them now that you can get them for next to nothing on Amazon.Interesting! It's possible it fell off if the meter is pretty old, or your power company just doesn't do it.
