copper wire

[Scruffy_Fly]

At work. There are 21 stores that most of them use a retrofit kits to use four foot T5 Fluorescent lights instead of T12 fluorescents. They all were installed about the same time I guess. We are experiencing a large number of failures of the electronic balast in each of the retrofits. I "retrofited" 8 fixtures to T10s this month. A while back I broke one of the ballast assemblies open. Found about 8 small transformers in it that used copper and red colored wires. Some of transformers are not worth messing with as the assembly has been coated with a varnish. The wire you get off them has lots of twist and bends and small hunks of the varnish stuck to them once you get the wire unwound. A couple of days ago I decided to give another go at some of the other transformers. These stripped of a lot cleaner. The wire diameter is about that of Uni Brassie size wire.

So lets see ..... 21 stores with about 10 fixtures per store and one balast per fixture. Wow! about 10 life times worth of brassie wire.
