Here's a pix of what might be considered nostalgic electrical metering. These are inside meters, which is a rarity here , and incorporate the small 6-banger 50A panels (3 breakers on the left on A phase, 3 on right on B phase) The particular job is a 5 unit apt house (6th meter is the house meter) . The place really hasn't seen a sparky since God wore short pants , but it's all tickin' along like time stood still. Any clues on the time frame when these were popular?
Wow, I cut my teeth in the biz dealing with those setups in Bergen County (Northern), NJ. I can't tell you how many of those jobs I encountered. I got to know the Square-D "QO-612" panels pretty well in fuse panel replacements. It is hard to believe that such installations still exist after my 30+ years and are sustaining today's electrical requirements. I'm sure that there are literally thousands of them out there between Baltimore and Boston at a minimum.
I remember encountering single-pole, 50 amp feeders to apartments in NYC. When was the last time that you encountered a 50 amp single-pole breaker? Oh boy, how times have changed.
Slightly off-topic, How many times have you been in an area like this, where you need to do some work in a panel and the area is so poorly lit (or the one light that is installed is poistioned in such a rediculous place, it leaves the equipment in a shadow) that you either have to wear a head torch or resort to the old torch in the mouth trick? One thing that I am really against as an inspector is poorly lit electrical rooms. It's just slackness on the part of the electrician.

Persuant to lack of lighting, you would LOVE our MDP. It's a 2000A (mains rating), 208Y/120 I-Line switchboard. Located in the seating area of our auditorium, the nearest light is behind it... and those are recessed can lights. There are lights in front of it, but the architecture prevents them from being useful (plus they are 25-30 feet above you). Better bring the portable lighting! Oh, and there is NOTHING preventing a patron from, say, turning off our 600A chiller; oh and it's directly adjancent to our fire exit. Grr to bad safety design... \end tangental rant
