    BS7671 524.1, C2 or C3

    Oh dear, what was happening hear, how could anyone consider even 0.5 mm² cable with a 3 amp fuse was potential dangerous? I must admit there does seem to be a difference in some books and paperwork as to what is and appliance and what is an installation, I would have said cooker hoods...

    Regulations for 12V / 240V wiring in campervans

    Since every time the camper is plugged in the ELI will change, many of the tests are pointless. You have a supply to fridge, some sockets, maybe central heating, maybe water heating, maybe lights, and the charger. What causes a problem is the 12 volt side, but no need for occupancy relays like...

    Nest 3rd gen thermostat power supply

    I know my Nest says it is hard wired for data, not sure how it knows if to use the 12 volt supply to send data, but may be because it is 12 volt not 5 volt? But easy way to get power is swap the socket for a socket with USB outlets, I have looked at getting USB power to a wall mounted item, and...

    Charging batteries and battery voltage?

    I have used a charger like you describe with a narrow boat, but it was designed for a flooded battery, where I could top up water level, 35 amp is a massive charge rate and OK with 3 x 140 Ah batteries for domestic and 1 x 140 Ah for engine, but the charger I have is designed for VRLA or AGM two...

    Do AC powered wireless thermostats exist

    I know Nest Gen 3 allows you to power up remote until using USB, it is basically a battery eliminator, and in real terms you can fit a battery eliminator to any thermostat. But if I look at my own system, the Nest Gen 3 is hard wired with a 12 volt DC supply to thermostat, but still have 18 AA...

    Can someone please clarify EICR rating of these downlights in terms of fire rating

    If a tradesman or professional strays out of there remit it can cause all sorts of problems, I had a house buyers report on my house before buying which detailed what had been found on the electrical system. It said the consumer unit had been up-dated and the old fuse box had been left in place...

    Battery Discharging on Vehicle

    I was going to say 4.6 amp is around the field current used by the alternator, normally the diodes in the alternator will stop it discharging when engine is not running, however alternators do use varying methods of control. French cars in the 80's used single phase alternators, and some odd...

    Charging batteries and battery voltage?

    OK I was an auto electrician back in the 70's and 80's so under stand a lot about batteries, however at that time the sealed for life battery was rather new, and you may have had a VRLA in a fire alarm, but not in a vehicle, the AGM battery was unheard of. So did have stage battery chargers for...

    Can someone please clarify EICR rating of these downlights in terms of fire rating

    I have never trained as a fire preventative officer, and I don't see that are part of my remit when doing an EICR, I may put it in notes, but if the lights were removed and the originally ceiling rose fitted and holes left in ceiling would it fail an EICR, no it would not, so simply nothing to...

    Do you ever feel so Stupid

    This is the problem when use to working on AC with no polarity, when you work on DC where it matters you get caught out. I did it with a Dynamo, always worked on Lucas and the field was live, but every other make the field was chassis, so I flashed field to live instead of chassis on a French...

    Under floor heating issue

    The UFH is limited to a floor temperature of 27°C and is background heat, the water is recirculated around and around the system, and once it cools a bit more hot water is added, the motorised valves on the UFH look more like thermostatic radiator valves, they do not look the same as motorised...

    What qualification is actually needed for EICR on private rented? Race to bottom.

    I have looked for a government site with a copy the the "check list" can't find one. I can find organisations who have published one, but not an official government one. While hunting I did find a memorandum which says what they expected, and this seems to say at least 4 years in the trade. See...

    Sockets in bathrooms

    I have looked at that, how do you know from that picture if the shower is in the same room as the socket? It is all down the the hight of the shower cubical door and if it reasonably seals at the top. If the door is over 2.25 meters high then it would be permitted. Don't get me wrong I don't...

    RCD types, what is the real story, should we worry?

    I have also watched the John Ward video, but the question is how likely is it to get DC? If a diode fails on the supply to a switched mode power supply, then maybe, but would it still work anyway? It is all well and good talking about a railway using 100's of amps DC, but my local railway still...

    Sockets in bathrooms

    Accessible yes, but when it did trip it took me ages to find it, last place I expected to find it, within a foot of the shower.

    New smart meters to turn off supply remotely

    Across the road from me, the milkman decided to use an electric van for his round, Renault Kangoo long wheel base, it is claimed to have a range of 100 miles, his round is 68 miles, so a reasonable leeway, he gets recovered around 3 times a year when Police stop him crawling up local duel...

    Sockets in bathrooms

    I know in mother's old house it did not comply, the socket was likely only 2 meters from the shower, I really do not see a big problem when the floor is carpeted and one is unlikely to really put anything too close to the shower cubical in the bedroom, it really makes no difference if the socket...

    RCD types, what is the real story, should we worry?

    I made a mistake, I bought a new consumer unit, and 14 RCBO's all marked on the box type B, did not really want type B I felt type A was good enough, had it fitted only to find RCBO not type B but curve B and type AC, so ordered 2 type A RCBO's for the main ring finals, and think that is likely...

    Can I sign-off work?

    From English government It also gives average price at £155 for an EICR. But I have hunted for some thing saying you must have x qualification and have failed. I bought my house last year, and before buying it had a house buyers report done, as part of the report it commented on the...

    Nest 3rd gen thermostat power supply

    I was under the impression that the thermostat sensor has to be in the circulating air, the idea is thermostat is opposite to the radiator, and since both sight and manipulation is required should be 1400 mm from floor level, you must have very tall toddlers. OK I will admit my Nest 3 is not...
