I have 2 MCB's at 6A one for upstairs and one for downstairs.
I am adding some lighting for under the kitchen wall cabinets although am not sure whether to go for small fluorescent or ELV spots. I just want to check how to do a calculation to make sure the load is permitted.? is it purely adding watts used divided by 240v = current.
One other thing I need to do is relocate a switch for 2 normal ceiling lights. The switch has 2 physical switches on it and is supplied by 3 core + earth. The switch has L1 + L2 + common on top and bottom. Hanging down from each ceiling location is just one 7mm wide cable with L + N + E
What are my options here as it is difficult to start ripping apart the ceiling and I can see no junction box where these 2 cables must meet. Upstairs in this location a granite floor is laid. Is it allowed to permanently make the switch live then put a cover plate on it. So then I would only have to make a new route for the new switch and cable up to the ceiling light point.?
Any advice welcome
