Being in the education side of the electrical business (UK), I am always looking for ways to keep the interest of my clients. Here is a picture of a 32amp MCB that I opened up. When set I can spring the breaker and open the contacts.

Has anyone got else got picts of equipment that can be used to explain how they work?

I have a clear covered 20 amp square D QO. I will send in pics.

I see a number of violations here. Improper means of support. not following installation instructions. orientation of the breaker handle [Linked Image]

only kidding, nice!!

XO breakers have clear sides. You can get cords with clear moulded plugs (one one usually with a neon indicator light).

Here are are some more violations. just for PCBelarge [Linked Image]

No honestly before I taught housewiring I used to teach repair of white goods and these are a few of my teaching aids. They do all work, and were made by the students. It was good to see inside the machines as they worked. The fridges I could over charge and under charge with gas to let them see the effects on the machines.
