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 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?

COVID Update: Emergency Work is Okay; Sitework is Okay 2 meters apart, Work in customers homes in general unless emergency is a NOGO. I'm trying to find the video and or article where PM questions were extended. Kids who live with parents at two seperate homes can still go to both homes...

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

Emergency light remained on when power reconnected. Switched to off, now not working. New battery, supply 232v, fuses ok. LED indicators not on Any suggestions, thank you

Ok, say you had a building that needed backup power. Does British Code require that the loads be subdivided onto different branches and automatic transfer switches based on type and priority?

I am looking for a product to convert an existing lighting circuit in a communal stairwell to be emergency battery backed up. There are 6x 7W LED mains fittings, so say a max 50W load. I could just add emergency lighting fittings, but wiring and access is difficult. It also needs to have a...

Having been at present place of work, for just overs a year now,just started to feel comfortable with the place. It’s predominantly a care home, and has all the normal infrastructure in place. I've never down much work with emergency lighting, other than installing it. Can anyone explain the...

I’m replacing emergency light fittings which have three terminals L-N-E, with new fittings which have four terminals (permanent live, switch live, neutral and earth). I only have a switch live going to these lights which is from distribution board to light switch then to these lights. Will these...

Just had an unsolicited call from this company trying to sign up electricians for emergency call outs. Got bored listening to the girl reading out from a crib sheet but suspect it’s another one of the many companies out there want to take a major cut of your hard earned wedge for taking a few...

Hi, I need help wiring my electrical key switch and contactor panel. I’ve wired my lighting circuits back to my fuse board but left brown/black out and taken them straight to key switch. Taken brown from breaker also to feed the key switch. What are my connections at key switch? Also what do I...

Been a while since I installed emergency lights as new. Bit rusty. Now I’ve got a few rooms to wire in a building that are going to be rented out commercially. I’m upgrading the db, to allow for expansion when other rooms start being worked on. The customer just verbally told me what he...

Hi I have installed a lighting circuit which has emergency with (integral battery packs) and non emergency lights on the same circuit (from the same MCB). The are wired in PVC twin and earth cable. The British standard for emergency lighting states the following, IEE Guidance Note 4 refers...

Hi Everyone. Working on a self contained emergency lighting system. There are 70 emergency lights over 3 floors. The emergencies are wired on a separate circuit from the local lights but fed from the same DB. I require the supply for the self contained (batt back up) lights to disconnect...

Bit of advice I have converted T8 etc florries to LED in the past no probs, but will there be an issue with a fitting with an emer pack, I ordered the ballast type in error from TLC, so need to get clever as I want a trial run on site to see if LED will work out in a hotel kitchen

Probably a silly question but is there a plug in option for 4 pin 2D emergency/maintained bulkhead using the existing control gear and batteries, if I plug in a 2d 4 pin LED bulb what will happen??:)

Anyone have a one line diagram of a typical UK or EU hospital? How are the emergency branches divided per code? How many ATSs? What is typical?

emergency lights not coming on when breaker is switched off, are these wired just for use as normal lights rather than emergency??? Sorry not done much emergency lights before

Is there any software that will enable a rough drawing of a building layout which can combine photo metric data? Possibly a free software from a lighting manufacturer?

I replaced the emergency lights in a small block of flats about 6 months ago, but the last time I did a 3 hour emergency light test was a year ago. Common sense says that I don't need to test the new emergency lights until they are a year old, but any clarification appreciated?

It's been a while since I tested emergency lights and I just wanted to clarify something. If the lights not working and the green LED light is off, is this an inverter and if the LED light is off and the lights still not working is this a dead battery?

Good morning all, I have a question about emergency lighting and the requirement of an indicator light stating that it is on mains power and charging. The centre that I work at has been refurbed and new LED type emergency lights installed at very high level, I don't know what MCB's control them...

Kindly refer the attached Image. There are 2 Places at which I can give reference signals for Emergency lighting. 1. At MXC 2. At LTC (Unswitched & Switched) What is the difference between the above two? why there is a need to provide input at two different locations?

Hi all, been a while - hello! A question for the collective brain - I'm about to do a series of inspections on an ANIMAL hospital. This in itself has always vexed me as to how to apply the special location medical rules as 1) a critical life-threatening operation is the same whether it's...
