What circuits am I missing?

[PrenticeBoyofDerry]

So how do I check? Turn the power off and just pull out the MCB? And I should see some wiring coming in behind it?

Isolate board, remove cover fixing screws and then cover, no need to remove anything else, just look to see if conductors possibly red are terminated at the MCBs in question.

Assuming the affected mcb's are have wires in them and your house is wired properly (i.e. not joined line/live wires form multiple mcb's.)

Best thing to do is turn one mcb off that you are unsure about and test everything to see if it is still working.( door bell, burglar alarm power light, smoke alarm power light, all kitchen appliances, boiler, sockets, lights, etc..)

Once you have found something is not working, turn the mcb on and see if it is now working; if so you have identified what the MCB is for, other wise repeat until you identify what the mcb operates.

Repeat all of above for any other mcbs what you are unsure about.

Also to further help you - B6 MCB's are for low powered circuits like lights, smoke/burglar alarms, out side lights, boilers, door bells, and possibly small kitchen appliances like fridges and extractor hoods where as the higher rating ones like B32 are for things like sockets, electric ovens/hobs, some electric showers, some electric heaters and any other high powerd device.


Lastly, does your house have electrical points/junction boxes outside for an conservatory or small extension what may pre-wired and built into the house should one wish to have a conservatory fitted?
