    Shower in a petrol station?

    What is the main RCD, as we are perhaps talking about a slightly smaller setup than I was thinking, I'm guessing we are taking 61008 time delay, at either 100mA or 300mA? At least with that the main trip will provide the 0.2 disconnection times for the final circuits (even a time delay RCD till trip within 200ms at 2XIn*) This is from 61008, I'm never sure why we dont need to test it at 2xIn *shrugs* ...follwing on from this one would expect if the required current to acheive disconnection time is 2x RCD rating, that the max zs for the cirucits should be stated as 50v over 2x In on the paperwork (rather than 50v over In) , however I've never seen that in any text book, its just what makes logical sense to me Anyway, a bit moot as you need 30mA additional protection for the shower, while normal practice is to use DP RCBOs, the designer might accept a lack of descrimination in terms of N-E faults by arguing: a) there is none on any of the other rcbo circuits, and the cirucits on MCBs will take the main trip out on faults anyway b) N - E fault on the shower is unlikely and if it does occur, the user could easily isolate it at DP switch and reset, unlike say an outside lighting circuit c) the services that would be lost are maybe not that critical in a smaller station, loosing the fuel console and the card reader is still a pain when folk have just filled up and want to get off though, but I'm guessing there won't be servers or anything else like that Not sure if hager do DP RCBOs for their boards, some other makes do, they take up two spaces, so if the cirucit is on 1L1, it'll also occupy 1L2, but where the second busbar terminal would normally be on a 2 pole device, there is a void space for the tab to slip into and no connection to be made, and a flying neutral comes out somewhere as per a standard RCBO. The output terminals are much easier to connect to than a single module RCBO as they are not stacked on top of each other To summise, I wouldn't design a new installation with the N-E discrimination problem, but I'm not sure I'd worry about adding one circuit to an installation so designed,.

    Pleasant 20 degrees and sunny. There are advantages to being a long way north.

    A new high .............

    Our hall is now 29.3 degrees C - with no windows facing the sun ............ The van showed 35.5 degrees this afternoon after driving for about 2 miles Yuck Thankfully no loft work this week

    Introducing

    Hi All by way of introduction I’m recently retired following spinal surgery and looking to stay active and renovate a property in the South East. I have a basic understanding of construction but lacking awareness of specific regulations and I’m weakest in the areas of heating and all things electrical: Specifically looking for guidance and steers to help me do what I can learn and also to understand what I need to leave for others.
  11. Given what you have written I would recommend you consult a local spark
  12. Hi All. My first post so please go easy on this novice. I’m responding to being burgled last week by adding more security to my house including one or two Amazon Ring Security Camera / Floodlights.... which require hardwiring. I’ve watched a few installation videos on YouTube and haven’t found a UK version that addresses all my needs. Most significantly, I don’t have an external light to replace so for this new installation I’m assuming I need to make a switched spur connection to my ring mains power circuit. This sounds like lifting floorboards ( necessary or avoidable?) and also drilling through the external cavity wall at the site of the external light mounting. I’ll welcome inputs to confirm if this is exactly what’s needed and also around the following... The installation instructions refer to the need for a junction box. Is this the same as the switched spur unit or something else. I’m unsure about this based on the way another PIR floodlight has been configured to include both a switched spur (as above) and also a small metallic round one gang conduit box on the external wall from which a very short run of wiring to the PIR fitting connects. (This may be solely due to the floodlight fitting having no mounting other than holes for wall fixings). And so if the mounting for the new fitting can be attached to the wall face at the site of the exiting wiring, I’m assuming that I don’t need a one gang conduit box. All said before I make a start on anything I’ll welcome informed guidance to make the overall plan together with anything else I may be missing. Thanks for reading.

    Shower in a petrol station?

    Mine excludes petrol storage equipment, but includes shops and offices. I have just queried with the insurer and they say as long as I am not touching the forecourt equipment it is just treated as a "shop" and is covered.

    Non, je ne regrette rien

    100% agree, and not just when you are older either.... some people think they can barter with you .... which won’t work with me

    Good point about insurance I will check that before I agree to the job.

    Shower in a petrol station?

    check your insurance too - mine specifically excludes filling stations, which isnt exactly defined but could easily include associated buildings

    Shower in a petrol station?

    I'm thinking a 40A MCB in the Hager board ..then a remote 30mA RCD for the shower . Can't see what else you can do TBH . If you do anything else there you'll need to up your insurance to £100,000,000 cover
  18. Well done pleased for you but this is an English site? How can we help?

    Interesting. I didn't perhaps pay as much attention as I should have, The DB is a Hager 3 phase board and it definitely had an rccd as the incomer. All existing single and 3 phase circuits are just simple mcb's. Single phase circuits appeared to be on single pole mcb's and that is what I was planning for this shower. Indeed I am at a loss to know how you would connect a 2 pole mcb for a single phase circuit into a Hager 3 phase board?

    Shower in a petrol station?

    Normal setup is TT, petrol station uncommer unit which contains an MCCB with earth leakage shunt trip, often with a label saying they should be adjusted to consultants spec, but normally found wound up to full. RCBOS fitted are nomrally double pole in order to avoid a N-E fault knocking out the main trip. In older installations it might only be sockets and forcourt equipment with a separate rcd/rcbo to meet the 0.2sec disconnection time (the main trip is normally set up to meet the 1sec disconnection times). however as all final circuits <32A require the reduced disconnection time you generally need an RCBO (double pole) on all circuits.

    Thanks Deke, that is what I thought but wanted a sanity check. I will use whatever earthing is there I am not going to mess with the distribution system, just add one circuit to the existing DB. One would feel certain that it has regular EICR's and any non satisfactory items have been dealt with. Just an EIC for my new circuit making it clear that is all it covers.

    Non, je ne regrette rien

    That can be very true ...I charge the same as I always did ...same petrol goes in the van ...same road tax ....I just don't put the same hours in anymore.

    Shower in a petrol station?

    Not done any petrol station work for years but I can offer that , as I remember it , the shop is normal wiring , TN-C-S ( PME) supply is not permitted , special areas are obviously the pumps and possibly the canopy . I'd guess you'd be fine working in the area you describe . Someone will probably have petrol station experience .
  25. I have been asked to install an electric shower in a petrol station. The room (currently a toilet) is accessed directly from outside and will contain just the shower and a changing area. There is a 3 phase Hager CU already with RCD protection and spare capacity in a corridor just backing onto this room, and a loft space above it. so it looks to be a straightforward job. But I am just asking if any other regulations apply as it is part of a petrol station building. I would not be doing any work on the forecourt or to any forecourt equipment and not even doing anything in the shop. So would any other regs apply other than normal bathroom stuff?

    Wall switch with red lights above it

    Possibly some sort of programmable security light timer ?
