Well, if your only talking about a few amps I think the "heating" is down in the noise. Tubular lamps are often fed from wires that do around the metal frame of the light fixture.

Is this product a rip-off? It's at least a good laugh.

We were talking about residential application, therefore 10 Amps is reasonable load to test. I think CEC talks about 100A and more and then cutting the slots or using non-conductive material. I do not have any easy setup I could do for 50 or 100A, but if opportunity showes up I will take it.

Wires simply coming out of a box is not that much of an inductive area. For example, this situation exists on most power company distribution transformers. Where I think more concern is, is when conduit is used, or the hot wires are running along side other wires.

I agree with you, we have done a little exercise in the school lab, we ran three wires, all connected to the same phase, loaded at close to its capacity (~15A), the conduit became warm fairly quickly. It was apparent that there was more heat then just heat generated by the resistance of the wires, although things are deceiving some times.
