Sumitsubo:
The wires you are referring to is the dimmed power cables to the LED lightning, which are operating at 9v. I think the voltage might be lower as I dim the light down. So then the high voltage is separated as much as possible inside that box.All the components inside the box are mounted on a metal plate (isolated between) which is connected to AC ground. Is this the kind of shielding you are describing?
Thank you for telling me about this issue. I had a feeling that this was not so good for long-term use, but I thought it was ok as long at the board was standing still. The box is wall-mounted so I will have to look for a better long term solution.
Hi again,
I downloaded the manual for your light dimmer and it indicated that the voltages varied (set by dipswitch) from 40 to 100 volts depending on the current and then used PWM for dimming.
Take note of my comment about AC and Pulsing DC in wires, although to a lesser extent it still happens.
Elecrtomagnetic Waves are like light so if you could shine a light from one wire to the next then they are not shielded.
Unlike light these waves can be stopped or reduces only by a metal wall that is grounded.
Sorry but no nounting them to a flat metal plate is not shielded.
Just a bit more on those waves, they are made stronger by the voltage in the wire and by the current carried by the wire.
So a wire that carries a pulsing 12v at 1 amp will have a stronger field than a wire that has 6v at 1 amp.
This is a VERY SIMPLE explanation of what is called electromagnetic interference.
Finally as i mentioned before your protoboard/veroboard no matter how its mounted is just for prototyping. Not for continued use.
