    RCBO tripping next door RCBO

    Testing an RCD on one rfc upstairs tripped the upstairs and downstairs circuis, which was the RCBO next door to it. Turned off the power to all circuits tested downstairs RCBO on its own RCD failed 1x and 5x tests. Disconnected conductors from this RCBO tested RCD at the board worked ok. Put...

    RCBO will not turn on

    Hi all, I'm having a problem with a newly installed RCBO. Having made alterations to a lighting circuit in a bathroom I recommended to the builder that the MCB on a 16th edition consumer unit on the non-rcd side be replaced with an RCBO as per 17th edition. I completed continuity ok...

    Wireless Programmable Thermostat wiring help

    Hi all, Today I found myself attempting to wire up an ESI ESRTP4RF Wireless programmable room thermostat to an Ideal Standard combi boiler. I believe it is now wired up correctly as the heating is coming on and off when I have it on manual and raise the room temp. I just need to put myself at...

    Why was it so popular to joint the CPC's outside junction box back in the day, answers on the back of a postcard please? I guess they never made junction boxes with enough terminals.

    EICR coding

    I would like you guys to give me some input on what to code this picture as, I was thinking C3. Also, I'm not sure whether the main earthing conductor and main protective bonding is 6mm or 10mm. They were both the same. Forgot the caliper today... I'm erring on the side that it might be 6mm...

    Consumer unit 10m away

    TT installation, looks like 16mm 2 core swa dno supply cable overhead into house? Might be smaller, definitely not bigger. 100amp type 2 main fuse new consumer unit into house approximately 10m away. In my opinion supply cable seems small but that's what it is. Now I should probably use 100amp...

    NICEIC Certification Scheme NICEIC Online Certification Rated Time Delay

    Could someone who uses this software tell me what the Rated Time Delay box is for when filling out the Main switch/ Switch-Fuse/ Circuit-breaker/ RCD section of an EIC? Is it for the recommend range in which a time delayed rcd should trip 130 - 500ms... or is it something else?

    interconnected circuits

    After installing a new consumer unit, both rcds were tripping out. I had a hunt around for the problem and quickly found a link between the first floor lights and the ground floor lights. Seems the hallway ground floor light had a link from its common terminal to the common terminal of the other...

    Continuity Testing reliability

    Friday I was getting continuity readings from my tester which start with a reasonable figure then drop off the scale to 0.00. This tended to occur more on the existing circuits rather than on new circuits. can someone shed any light on this?

    2394/2395 to be scrapped!

    I read today that the 2394/2395 will be replaced with a 2 hour short answer online typing exam. I appreciate that it must be a nightmare to mark all the written papers but from my point of view the whole point of a written exam was that it made it tougher for the people taking the exam. I took...

    Exceeding the current carrying capacity

    Current carrying capacity is a figure which is given to us by manufacturers, correct? Now, I've watched those videos of the guy trying to set fire to a piece of 1mm and it takes quite a bit more current to set a light. So for example, if you had a 9kw shower and a 9.5kw instantaneous unvented...

    Accessibility of a low voltage transformer

    Have come across a low voltage transformer which has been placed in the ceiling above a shower not accessible at all which means the customer cannot change the time period on the overrun. I can't find anything in the regs that says the transformer needs to be accessible. Anyone have any thoughts...

    cables covered in bitumen

    I ran some cables down a wall today and then the builder hacked off a meter up the wall and applied bitumen because of damp which meant the cables got covered in black bitumen. Does anyone think that will affect the cable?

    3 lights, 3 switches, 2 switch cables

    Hi all, An interesting method which many may or may not have seen before is having 3 lights, individually switched but with only two twin cables at the switch, all in old colours. I was wondering what people think of this situation on an EICR or just in general? :lol:

    Microbore

    Does anyone know if its ok to replace a small double radiator plumbed in 8mm microbore with a new 500x1500 towel rail with 15mm fittings. I do not know whether the central heating system has manifolds or not, probably it does somewhere, I haven't seen them. A new combi boiler is in place. I had...
