Recently I got a call from a Condo Association I have worked for off and on over the years. They said the doorbuzzer/intercom system was repeatedly going out. This was a slightly more complicated than average system because it utilizes the phone lines. They had had it installed last summer. It worked fine all summer and fall but now was going out.
It turns out the new system has several transformers. The folks who installed it were not very good craftsmen, in my opinion. There was one outlet in the basement by the panels, and they plugged two cord strips into it and rigged the transformers with extension cords. That was pretty sloppy. But the kicker was, the outlet they plugged into was a GFCI outlet that had been installed to provide GFCI protection to the circuit that went outside and up the back porch to power the de-icing cable in the gutter. So when there was flooding and extreme moisture permeating those gutters, the GFCI protector tripped, as it should. You don't want 120v power "live" laying in soaking-wet metal gutters! Normally, after the severe moisture passed, one would simply re-set the GFCI protected outlet. It was never intended to be used for other loads, especially not an intercom system that controls the building entryway. Since there was an on/off switch right next to the GFCI outlet, so that the de-icing cables can be turned off during the summer months, I would have thought the idea of plugging an intercom system into it would be off the table. Just by the co-incidence that no one at that condo association was paying attention to these things, and the de-icing cable power was not turned off for the summer, that the system worked in the first place.
I installed an array of receptacles so that each transformer would be plugged in separately, and all of them are now powered by a new, dedicated circuit. Big improvement.
If you live in a condominium or multi-residence building, it is a good idea to be sure all of your critical systems, such as furnace or boiler, hot water heaters, and door buzzer/intercom systems are on separate dedicated circuits so that if something unrelated goes down, you are not left out in the cold!

Last weekend I had the chance to meet a lovely lady in Andersonville who had purchased these beautiful fixtures. She found me on the internet by searching for old wiring experts, since her building is from the 1920s. She had been concerned
that the old wiring may not have been dealt with when the condo conversion was done. She was right, there were still some cloth-covered wires in use above the old fixtures. Fortunately, in this case they were not nearly as deteriorated or compromised as they usually are, and we were able to work with them. She was lucky; that is hardly ever the case. But by installing white extension boxes, which added an inch and a half of wiring space, we were able to keep the old wires in use by creating a cavity for them that would not force them to be crammed and jammed into tight quarters, which would both do damage to the insulation and restrict air space for ambient temperature cooling, which is vital in ceiling fixtures. These extension boxes were clean and white, and are hardly noticeable.
She was very pleased, and I was both glad to have a great new client and a tad envious of her beautiful lighting. She has excellent taste.

I am very proud of my crew. They removed the old decrepit 100 Amp Service and installed this brand new 200 Amp Service in very cold and challenging conditions. The two circuit breaker panels are furnished with brand-new GE circuit breakers. We re-routed all of the wiring that had been leading to the apartments from the old panels to the new ones and traced each circuit to identify the loads. We grounded the equipment properly as Chicago Electrical Code mandates. WE also converted the basement light switches so that the lighting could be turned on and off from multiple locations, one being at the back door. Very handy for coming into the dark basement at night! We also added GFCI receptacle for plugging in misc items as necessary. The electrical safety quotient at this building went up 110% after this job! The still have some cloth-covered wire in the walls, I am sure. But rewiring can not begin until you have enough spece in your circuit breaker panel to add new circuits. So they are well on the way!
Two brand new GE circuit breaker panels.
New meter socket with ground rod and leveled and plum 2" rigid conduit riser emanating from the far side.
Work in Progress. The two new GE circuit breaker panels have been mounted, and the two old panels and meter housings waiting for the circuits to be transferred, disconnected and the equipment demolished.
Old riser pipe. Strapped in a very careless fashion with dry wall screws. Can you say garbage?
Old service head with cables coming out of it. Note the cracked and missing insulation on the main hot wires! This job was more overdue than the clients knew.
