Just curious, what's an LVMD and what does it do? Googling just turns up Low Voltage Maximum Demand without much explanation.

It's the Low Voltage Mains Distribution board. In big builduings (e.g. offices, hotels, hospitals, ...) where you have multiple switchboards on every floor, the LVMD is where all the feed lines to those switchboards meet and are selectively fused with NH-fuses (like the one you see in the picture) and are connected through the main line to the grid. Often the power metering devices are stationed there, too.

Thank you for the reply! Sounds like you aren't in the US which is probably why I haven't heard of this. Thank you!

Must have had a bad connection, would change the whole switch. Edit: Yeah it's probably burned anyway just realised that...


vesElectricEyes

That's exactly what we did. The burnt plastic rendered it unusable to the point of not being able to properly switch it off. Getting it out was a piece of work too.

And it is smelling bad all the time while working on it.
