    Does polarity matter for an RCD?

    It's marked on the device: 1 - supply line 2 - load line 3 - supply neutral 4 - load neutral Depending on the application you have in mind for this RCD it would need to be installed in a Legrand enclosure with the correct busbar and MCBs etc. As it is second hand I would also recommend...

    MCBs Polarity ?

    When Nader MCBs first emerged they were marked 'supply' and 'load', but the busbar fed them from the top in some applications, after several months we finally got a Chinglish answer from the manufacturers that it didn't matter in AC applications.... Not that it mattered anyway as they were...

    Hi,what EICR code would you give for pendant light in a bathroom

    A lot of bathrooms never had showers when they were originally built, hence the name bathroom. And dependant on which version of BS7671 there were designed and installed to then zones may not have even been in existence.

    Selectivity to an outbuilding

    It's not uncommon to run a small supply, 20 amp for example, to run some sockets in an outbuilding then fuse down using an SFCU for the lighting circuit. And yes, they would be covered by the existing RCD. Not an ideal set up as a fault on one circuit would take out several more.

    SPD's & Submains

    Only needed where services enter the building. i.e. the point of supply.

    UK Split Load Consumer Unit

    Don't bother with split load, just use an RCBO board. However if the supply circuit is already RCD protected then you could just use MCBs. But as you're planning on an EVCP you need to be aware of the requirements for specific types of RCD and have the correct one for the charger. In this case...

    Scrap copper cable strippers

    I have one of these: Dirty dirty stripper... I only strip 6mm upwards but this can do down to 1.5mm. Paid for itself on the first run but I do get a lot of large offcuts.

    PAT testing certificate?

    I used to provide a PDF with all the test results on it. Just an Excel spreadsheet which was saved as a PDF.

    Electrician to install EV charging point.

    An electrician can install an EVCP however there's a lot of paperwork and hoops to jump through for registration, claiming grants etc so it tends to be more specialised installers that do it.

    MWC for changing MCB's to RCBO's

    Those C2's aren't justified IMHO. Also: Outside Light Damaged Schedule Item contravened: 5.20 - Adequacy of working space/accessibility to equipment (132.12; 513.1) How does a damaged accessory come under 5.20?

    Possibly the best tool in my tool kit! Batavia screwdriver.

    I use one of these as I do a lot of work in 19" racks with lots of cage nuts, it does up to 6NM which is ideal. Shameless Amazon Link...

    Cable size for car lifter ( ramps)

    I'd be tempted to do two 4mm radials on 25 amp C type MCBs to 32 amp isolators. As the circuit is clipped this will give the future option of upgrading to 32 amp circuits if required. Isolator rather than Cdo Skt as this will negate the need for RCD if installation method permits. As this is a...

    Is it worth it or even possible to set up as an EV charge point installer?

    There's a lot of competition out the installing EVCPs and large companies take a profit hit on the installation works to pick up remedials needed to allegedly bring the installation up to standard before the install the EVCP. I would advise against having only one type of workstream as a sole...

    First MFT Advice (Megger or Di-log)

    To throw another into the mix, Metrel do some good testers at good prices. The Mi3000 is a solid bit of kit.
