One of the switches is a 3 gang switch which also connect to some spotlights and outside lights. When turning on and off at one switch it is fine, but then if you...

    Are the 15A/20A wall outlet insides different at all?

    Hello, people. I'm a DIY guy, not a pro electrician. We know of 110 VAC wall outlets: 15 amp and 20 amp. Are the inside parts for a 20A any physically tougher / thicker / more robust than the insides of a 15A? Or, are they all the same, the only difference being that T-shape leg on the 20A...

    Max Zs values at different ambient test temperatures

    Hi guys, I'm currently revising for my 2391 and kind of confused on the temperature factors for the Zs values The BBB give Max Zs which are 100% values with a max operating temperature of 70c. The OSG and GN3 give values to 80% which are when tested at ambient temp of 10c according to page 146...

    Different kw readings

    Hello, I’m testing some electric meters. As the circuits have no load on them to prove each ct I’ve plugged a hair dryer to simulate a load and put the ct around the line of the hair dryer to check measurements are the same as a calibrated meter. The Ct’s from each phase read the same Amps...

    I have a street light circuit on land I rent out. I need to replace 2 of the bulbs. 1 of them is an old Philips 55W SOX Plus, the other is a Heathfield 30W E27 LED. I'm not sure if any electrical work was previously carried out to enable the Heathfield LED to work. Can I just replace the old...

    I was the 2nd sparks taking over a garden office supply job. The first sparks had fitted 10 sq mm 3 core SWA, but it actually had brown, blue and g/y conductors. The middle was also more like hi tuff in the sense the insulation surrounding the 3 cores resembled a cable in its own right not just...

    UK reg to say 2 different size cables cant be used on one circuit if rcbo rated to lower cable?

    Came across a cooker circuit with 10mm and 40A rcbo. Last leg was 6mm. Isolator to outlet. I downgraded to rcbo to 32A to accommodate the 6mm. Does the cable have to be the same throughout? If so what is the reg for this please. 🤔

    How many different brands in one board?

    EICR today on a holiday cottage. Suffice to say they’ve agreed to a board change along with some other remedials. I took the cover off…. That’s not one of the faults… but straight away missing busbar shield, mismatched devices no RCDs whatsoever and 1.5mm cable spurred off a 32A mcb.

    different make SPD in consumer unit

    Is there a reg anywhere that states that you have to use the same make SPD inside a consumer unit. I know there are with MCB's as they obviously have to sit on the same bus bar but an SPD just slots in and has flexible cables wiring it up.

    TIS Multifunction tester is giving wildly different ZS from colleagues DILOG

    HI, I bought the TIS MFT PRO from CEF, nice touchscreen etc, so in the future I could add on the EV dongle and have a fancy case and tester etc. But I can't tell if it's just wrong or crazy, or I am. My colleagues budget DILOG MFT's will test a socket Zs at say 0.42. But the TIS MFT even after...
