    TT advise

    The SWA doesn't need rcd protection (assuming the armouring is correctly earthed. The 100mA time delayed rcd isn't required by our regs but is advisable from a belt and braces point of view but would terminate the swa into this enclosure at the consumer unit end - otherwise the occupants would...

    Anyone here have links with Western Power training?

    My youngest runs the local hot glove team, they work hands on live on the 11 and 33kV network. NG (old WPD) have something like 34 of these teams accross the country each consisting of 3 or 4 people. Pretty sure that you can't just apply to become part of a hot glove team as a 16 year old. My...

    EV chargepoint charging providers

    I have a customer who has a holiday letting business sleeping up to 30 people. Fairly rural with limited charging facilities available locally. She is looking to install an ev chargepoint that her guests can use on a pay as you go basis. Any recommendations for charge platform providers...

    grade B ld1 conventional fire detection system

    At an Elex show a year or two ago the people on the Click Scholmore stand said that they will design and certify a fire system. Don't know how the certification works or what cost implications there may be but possibly worth a phone call to them. I was asking about a small HMO so I assume they...

    Dodgy PME?

    Round our way we have some areas which use very old cabling originally put in when the network was DC, the joints can't withstand the high fault currentsyou get with pme. I had a very similar job to the picture in the op. Three cottages built for the gasometer staff, no 1 was tt, no 2 homemade...

    UK Meter box too congested!

    The last couple of de-loops that I have been involved with had the single phase supply replaced with a three phase cutout (as I believe the DNOs have been directed to do) which could further affect space problems. This could be a bonus though as WPD had to change the meter cabinet as well on the...

    Will The Terminologies Start Changing?

    We went to see dreadzone a few weeks back, in the field there was a young girl sitting on a potty totally absorbed in her 'interactive presentation device'. I was going to take a photo as it was a sign of modern times that I don't really agree with but quickly realised that if I was seen taking...

    Domestic extractor fan wiring into a timer

    Elkay 2235A-1 Energysense White 3 Wire Touch Timer 16A 240V. This is a touch timer (you don't need that bit) which also can be activated by a pulse from the type of switch you have. The time on is selected by internal dip switches. You might have to house it in a box in a bathroom which...

    How far do downlight cans affect lamp life?

    The Evofire downlights you refer to don't have anything enclosing them so one would assume that they are good for heat dissipation. There is a version that is insulation coverable which has a skeletal metal frame over to lift rockwool type insulation off the lamp. Some GU10 downlights achieve...

    Loop into Fan

    I have posted this years ago, it is the way I wire fans which gives the fusing required by a lot of manufacturers and the isolation required allowing the light to operate when the fan is isolated, a lot more convenient at night if you only want the light on. Really only for new work or very...

    Soffit lighting

    Ansell make a downlight specific for soffits. It is Du Pont paint coated and guaranteed for 20 years. However the best thing about them is that they are tiltable which can be very beneficial as shining lights directly on plastered walls can show up any defects in the plastering. Additionally...

    Communal DB does it require RCD protection to be a sat EICR

    Think this is the relevant point. When I queried a similar scenario with Napit technical a year or two back I was advised that the communal lighting was not necessarily domestic in which case you are only coding for cables being less than 50mm deep (if that is the case).

    UK Change in current capacity along run

    Don't think it says change in current carrying capacity, doesn't it say change in conductor csa (which will affect current carrying capacity? There is a 3m rule for backfusing in this circumstance

    UK RCBO Testing

    Make of rcbo? Some (MEM?) were known to not trip when testing at their output terminals but attach even a modest length of conductor and test from that and they behaved.

    UK EV charger

    Looking again the conductor coming from the lh fuse and the lh n appear to be in heat shrink as does the earth. Looks a bit 'home made' as though singles may have been used and the heat shrink is there in an attempt to make the tails double insulated. Doesn't explain the earth though

    UK EV charger

    For clarity, the issue with a looped supply is that two supplies are connected to a single terminal in the cutout which is rated at 100A. Taking diversity into account this was considered acceptable. However with the advent of EV charging the loads have increased significantly and the 100A...

    UK EV charger

    It doesn't look like a looped supply but it is a bit unusual. Your supply appears to be the right hand fuse, the left hand fuse supply goes through the wall (to your neighbours?). It is probably worth contacting your dno to get them to come round for a visit as it looks as though your...
