New style Wylex board design flaw

 

[nicebutdim]

Is that busbar obstructed or is it the camera angle?

 

[SparkySy]

I think it's more the strange bent under the buzz bar backplate. That would hamper getting glands in the bottom, I don't get the reason for it though.

I think the OP might be talking about the neutral passing on its own through a metal hole and possible eddy currents.

I don't fit Wylex boards... but are you sure it's assembled correctly ?

ImpededLoop gets a Star
Neutral passing through a metal ring on it's own.

There is also little space under the busbar guard to use the knockout points provided.

Does the busbar cover still cover? Looks to clip really low down

 

[Chris Sparks]

Busbar cover fits well on these boards

Yeeeeeeessssss......... but is that separating panel actually ferrous?

 

[telectrix]

can't see eddy current/s being a problem in this situation. storm in a teacup.

My limited understanding - there are two scenarios at work:
1) eddy current loss due to Faraday's law, similar to having the first turn of a transformer. As it's a low frequency (50Hz), large size of winding, tiny size of core, and less than 1 turn I believe this will be barely perceptible. In fact the parameters are all the opposite of how you design a decent transformer.
2) If two conductor's pass through the same sheet then the magnetic fields at 90 degrees are working in opposite directions, rotating back and forth with each wave cycle of AC. My understanding is that it's the friction of the two opposing rapidly rotating magnetic fields that that generates heat. Think of it like two circular saws attacking the lump of metal on on opposite sides.
In this example only one core actually passes through the sheet, so I'm struggling to imagine that anything would happen here at all. And as above it may be a non-ferrous plate anyway.
So I'd be inclined to agree that you'd wait forever for something exciting to happen due to that design.
