Dependant on what you’re trying to achieve I guess.
You can add sections onto switchboards, but if memory serves me you can only have one supply on at a time.

Most test kits are designed to saturate the sensing coil with DC, if you have a type of RCBO that is designed to trip Under these circumstances then that’ll be the issue.
There is no isolation for the gas other than the main isolation valve at the meter.
The Hob is being replaced by another person arranged with the landlord - I can only ensure that there is no immediate danger from the electrical side.
You’ll need to design this cable, if for instance you have a 9kW shower, 2kW electric radiator, plus some ltg &small PWR you’ll be having substantial Vd problems - circa 30-35v.
Depends on actual load, but I would advise you strongly to check your calculations.
I’ve seen similar marks before but there has always been a logical explanation.

Just been to look at a hob that has been getting hot above the electrical / gas connections. I was unfortunately unable to locate the source of the problem.
No visible damage to cables,
Zs fine,
RCD checked out fine,
IR >999 @500v,
And is still fully operational.
I’m Baffled, any ideas?
Ian you're thinking single phase, if the street/area is supplied with a 3ph+n cable and the neutral (PEN) is lost, you now have an unbalanced three phase circuit with no neutral.

Depending where the break in "Neutral" (PEN) is, you also have your neighbours loads to consider. Also, if a certain Entertainment provider is added to the mix it makes a hell of a mess.
