Concealed Power Supply

[Charlie_]

I need to get a 110v supply from a wall, through a door frame and into the glass rebate of a door..
Has anybody successfully done this?
I want it to be concealed so the little boxes with flexible conduit are no good.
I’m thinking of using power transfer hinges.
It’s to power smart glass in the door..
The windows are easy enough as they are all stationary.

Thanks Charlie...can't find a button for that?

Just a thought - keep it simple and use super flexible wire to bridge between the static and moving parts:

Rapid Extra Flexible Wire 25m

Rapid Extra Flexible Wire 25m - A very flexible wire suitable for test leads, interconnection and frequently being moved wires.

or this one for 'abrupt and fast movement applications such as cranes and robots':

What's a ball park figure for a smart glass window then?

All in the glass cost £20k.
Probably about 25 Sq metres.
I think the glass is also triple glazed.

What happens if it is broken - (may have been asked already) - is there any electric shock risk?

It’s a fairly new product so reliability is difficult to research, can only go on manufacturers assurances and guarantees.
I’m supplying the glass at 110v using an isolating transformer

Sounds out of my price range. I'll stick with curtains!

Far too elaborate. We don't have fancy things like that in Barnsley.

Round that neck of the woods they are most likely to be on the outside and made of metal

I would have thought that if supplied by an isolating transformer, the shock risk would be negligible if the output is not ground referenced.

in my opinion, the most dangerous electrical fitting in most houses is the good old BC lamp holder. possible to access live terminals without any special tool by untrained people often working in the dark.

Most of ours are plywood, so I instead of washing them I just sand them down every now and again.

I was thinking the exact same thing at the weekend, whilst stopping my daughter from putting her hand under a shade to switch a table lamp on with nowt in the lamp holder.
Which reminds me, there is something I need to do.
