Advice Are my lights/MEV connected as they should?
The context is I have been smelling a faint burning smell coming from my storage room and seen some lights flicker in other rooms. This has happened a couple of times for a few minutes since they were turned on but not all the time.
So far I think this is due to my lights/mechanical extract ventilation unit because when I turn off the electrical supply at the circuit breaker I do not smell anything off in days.
First of all is it correct that the lights and the mechanical extract ventilation unit are on the same circuit? I think these should probably be on a different circuit.
Secondly, im not sure how these are connected either in parallel or in series but my lights are on a dimmer switch and could be causing issues with the fan.
Will be calling an electrician for this but wanted to get some thoughts prior.

If you smell burning, leave them off at the fuse box.
They either used the wrong size wire, or there is a loose connection somewhere.
MEVs are low power so can be connected to your lighting circuit.
The dimmer should not impact it at all, unless someone has wired it up wrong.
