I have a boiler with a 20amp disconnect switch. The owner wants to add 2 mushroom head E-stops. If there is no e-stop terminals in the boilers control panel whats the best way going about this?
Can you use an existing lighting circuit (one switch operating one light fitting using twin & earth) to replace with maintained emergency lighting fitting with microwave sensor? The idea being that the switch becomes redundant due to the sensor, but can be used for the emergency switch test plate.
Hi All,
Looking for some advice, I have been issued a drawing of a large warehouse lighting layout. the drawing shows 72 high bay lights including 29 self contained emergencies. The specification from the manufacture details that the Protective device must be a C16 and a maximum of 3 lights...

Question we are replacing a consumer unit for a landlord and he's been advised by another company to fit

Ok I have a confusing situation regarding some Emergency lighting. I have a string of 2D 28w lights in a ward corridor at an nhs unit which are switched from a nursing station with a key switch next to them. It appears that the key switch only breaks the permanent feed to the Emergency fittings...
Hi
I'm not stupid got 93% on 18th Regs, passed all my exams easily, have a degree in Foreign Languages, used to be a teacher (God help me, don't ask) but Emergency lights confuse the hell out of me. I can't remember the difference between NM & M, switched and unswitched. Was replacing several...
Hi there,
I was wondering if someone could help me out with this. How would you go about operating normal lights with a maintained fitting ? eg, one maintained bulkhead and 4 Downlight's. A key switch with a separate 1 gang light switch next to it. The light switch to operate the bulkhead and...
This question comes about through a query from my mother.
Her church has been closed, rightly so, for the past 6 weeks. She pops in for cleaning etc. She has noticed that the electric meter has gone up roughly 12 units each week.
Without taking a special trip over, I’ve tried asking her what...
I'm looking at arrangements for lighting in a small room. It needs a decent level of low-shadow light when occupied, but as windows are usually shuttered it also need to have emergency lighting in case of a fault (not for long though, 30 min is plenty of time to fix or leave).
My initial idea...
I have cancelled all my jobs, but I conduct monthly light checks on blocks of flats, so I am planning on still doing them because I don't have to be inside peoples homes or near them (at least 2 metre separation).
Would others also consider emergency light checks to be essential works?

Hello, this emergency light does not come on when power is cut. There is a red light on when house has power, indicating power to the unit. The bulb works fine. I thought the battery may need changed. It has not been changed for a long time.
How ever I can't see where the battery is. Is it...
Hi all.
I work in a factory and do the regular EML light test.
The factory has had some extra racking installed.
This now covers some of the emergency twin spots.
I know where I can move some of them to better cover the area and have discussed additional ones to also cover the area better...
Hi, I am new to HV Electrical Stuff. I am trying to use a emergency stop button to kill power to BOX A remotely.
The wall socket has 3 phase 380V supply without neutral. I want to introduce a control relay between BOX A and Wall socket. The remotely operated cable (20 metres) with Emergency...
I want to make a power tool extension lead using an Emergency Stop Switch KJD17B NVR. However, this is a momentary switch (not latched) so the supply is not constant. Do I need the switch to operate relays that will feed a constant 240V? What would the wiring diagram be? what relays would I...
Hi
Just made up this drawing of a way to wire and test emergency lighting and keep the non-emergency lighting lit.
Has others wired it this way and would it be 18th edition compatible?
I've attached the drawing
Something is amiss at the Science Museum London, lots of the building have a varity of hired in battery LED lighting and the rest is closed due to urgent maintance... Sounds like they are needing a electrician or two and I suspect they are on a central battery installation.
Would anyone be so kind to provide a wiring diagram for the following ?
I will have the following per room
1 sensor, 4 lights ( 1 Maintained emg) and 1 exit
There will be a test kit at the switchboard
Many thanks in advance
