Hi,
Moved into this 100 year old house recently but the other day had an issue where burning plastic smell coming from meter/consumer unit cupboard. I checked it out and found that a now half melted 40amp rated fused connection was being used to split the post meter supply 3 ways to 2 consumer units and a Shower RCD. I have since replaced with a 100amp splitter but noticed another few potential issues that I wanted to get some advice on. In the pics below you can see the set up.
1. There are 25mm tails coming in and out of the meter but the main incoming wiring that you can see coming down in the top right looks more like 10mm. This would not seem adequate to me, given that it connects to a 100amp main fuse. As this is pre-meter is this the responsibility of the electrical utility or the homeowner?
2. At the bottom of the meter, in addition to the 25mm tails there is also red and black wires coming out and feeding the black switch in the bottom right which confusingly looks like a mains switch but is actually being used as a fuse for the light in this cupboard. I presume that the logic here was to have a light on to allow work on the consumer units while the power was disconnected to everything else but I am not sure that this is normal or acceptable practice?
