Roughly 135 miles (217 km) north of the City of New York, Albany sits on the west bank of the Hudson River, about 10 miles (16 km) south of its confluence with the Mohawk River.

NYC Rapid Transit’s 45-Ton Rotary Convertor

|

A rotary converter is a type of electrical machine which acts as a mechanical rectifier, inverter or frequency converter. “Rotary converters were used to convert alternating current (AC) to direct current (DC), or DC to AC power, before the advent of chemical or solid state power rectification and inverting. They were commonly used to provide DC power for commercial, industrial and railway electrification from an AC power source.”

I think it's fair to call this device old sparky.

My favourite industrial connector (Ceeform).

For simple rugged power distribution it's hard to beat these rugged Ceeform connectors. They're available in a range of current and voltage ratings with suitable colour coding and keying. They're so common that they literally only cost a few pounds each in quantity for the basic blue/yellow 16A plugs/sockets.

They can be dropped from height, dragged across rubble and left out in arduous weather conditions without too many problems. The fact they're made of resilient plastic with long overlapping lips means that they can be handled relatively safely in wet conditions.

One thing I didn't mention was that the black bodied connector is specifically designed for the entertainment industry where it blends in better than coloured connectors.

I love these connectors. Easy to wire and super-rugged. The most common problems I have with them are broken wires or very rarely a welded contact on higher current connectors. They're cheap and common, so easy to keep spares in stock. Swap or reterminate and they're back in action.

I have seen these in the Empire Plaza and was wondering how they worked and the benefits of them for connecting and disconnecting high voltage, high current loads.
