    Help identifying dimmers

    If they are just dimmer modules mounted on a plate, I might be inclined to replace them with a couple of Varilight vPro dimmers. You can buy just the dimmer modules for just such a task. Unless they are hugely customised and rely on non-standard control shaft diameters, you should just be able...

    Quinetic & flood lights

    Does the switch have a neutral connection? If not, this is why. For the switch to generate the power required to operate the electronics, it has to pass a current through the load in the case where there is no neutral connection, with older lights this wouldn't have been a problem but because...

    UK Zs readings unusually high on new installation, what is the best option to lower them?

    If you are using a 3 lead test through and RCD or RCBO, those devices could be adversely affecting the Zs readings. The way to see is do a 3 lead test at the input terminals of the RCD/RCBO and then at the output terminals. If they are wildly different, the device is the issue and I would use...

    Connector type identification

    From the looks of it, the connectors are clipped into moulded housings and may just unclip with a little gentle persuasion. What makes me say this is the small pawl/barb style mouldings at the tops of the recesses in the front panel... they appear to be retaining similar mouldings on the...

    Dodgy trade pictures for your amusement! - 1 Million Views!

    HiTuff (NYYJ) doesn't have a metallic sheath, it has an insulated CPC... at least all the HiTuff I've ever bought has. If the insulation on the live conductors is silicone rubber (it looks like it might be), it's an FP series cable unless I'm much mistaken.

    Connector type identification

    You're better off looking for battery holders and replacing the whole thing.

    Thought I found a nuisance trip but I didn’t. Any advice to my questions...?

    Did you ramp test the RCDs with nothing connected to them to establish whether they are conforming to specification (trip current around 25-26mA)? When you say he has a lot of stuff plugged in... how much stuff? and perhaps more importantly, what? If it's a lot of electronics via plug-in...

    Nvq for cps membership.

    @BruceBanner , I had the conversation this morning... essentially there is a limit of 2 years in which your last assessment report can be used as evidence of relevant experience after that you need to meet the new member joining criteria. Unfortunately they phoned me at a somewhat inconvenient...

    I tried several times to get through to them yesterday but kept getting a recorded message telling me they were unable to answer my call, so I'm waiting for them to call me back.

    Am2s Continuity Of Protective Conductors

    @mpratt263801 , The point we're both making is this, there are two tests you can use to establish whether or not the CPC is continuous. These are commonly referred to using the results they provide, which is the R1+R2 test (typically performed by linking L+CPC at the board and then taking a...

    UK Rewire using old conduits

    If they are the usual old thin metal ones in the wall, you may struggle to reuse, but if you can do. I've just completed first fix on a rewire, chose not to and chased... switch heights were quite varied so standardised and also wouldn't have been able to get all the cables down them (I usually...

    Minor work certificate

    I would argue that 'touching' in this context is only applicable if you have made significant changes to the fixed wiring... i.e. taking a socket off and doing some testing is not a significant change to the fixed wiring and therefore you've not changed anything. You could say the same thing...

    Two 16amp ovens on 32amp mcb B supply

    Just be mindful that technically, you'll be adding a new consumer unit and two new circuits which makes this notifiable works under the building regulations (Approved Document P - You can search for this on-line, 2013 edition is the one that applies to England). As such you should either go...

    What tests do you carry out to ensure they are continuous?

    Two 16amp ovens on 32amp mcb B supply

    If the manufacturer recommends 15/16A fuses, I would either (a) downgrade the protective device of the existing circuit and use that, along with install a new circuit for the other or (b) put a small consumer unit like one of the BG garage units on the end of the existing cable and put two 16A...

    Unfortunately, I've not had time. Things beyond my control... well... mostly.... me shoving a drill through two of my newly installed cables on the rewire I'm working didn't help, and today time has just run away from me. I'm not working on Monday as I have to be home to have our dead gas...

    What to do about a wobbly lamp holder?

    I'll also add, that if you are finding the threaded fittings are coming undone when they are mounted in solid items (not the cork) when you're moving the lamp, you may want to put a spot of thread lock on the fittings and then tighten them down. Loctite make a variety of different sorts, the...

    What to do about a wobbly lamp holder?

    If the one with the red cable is mounted in cork, you will never get a secure fitting without using large metal washer/plates to spread the load. Cork deforms far too easily to form a solid mounting for anything. In the other case, I suggest you invest in a decent hacksaw and cut the threaded...
