    Question regarding dead polarity test. Please Help.

    Hi I am bit unsure when carrying out dead polarity test on a one way switch and two way switch. Where do the test probes go and on what? Do we make contact at the switch line and the cpc of a ceiling rose? or do we contact at the line and cpc at ceiling rose? What happens in two way switch...

    Level 3 Testing. Is this right?

    Hello I have my 302 Practical exam (testing) on Wednesday. I just wanted to know if I am right in what I'm doing. 1. First you would do the Testing of the Protective conductors. Using the R2 method (Long Lead) 2. Then you would do the R1+R2 Tests of all your circuits. Connecting Live and Earth...

    polarity test

    Hi, I have just done a IEC check. It is a normal plug plugged into the mains, then on the other end, it's been wired up to a double socket. It passed the earth, and insulation but failed the polarity test. Im gathering that means its not wired correctly and needs to be taken out of service until...

    Head Scratching time lighting fault

    Been doing an eicr today, went to do an R1+R2 on a lighting circuit and got no reading between earth and live but neutral to earth was 1.36 ohms. Straight away thought reversed polarity, but the luminair was working correctly before we arrived, so i put the power back on and checked the voltage...

    Questions regarding polarity and continuity for a light circuit.

    I am trying to find out where on the light switch or the celling rose of a light is the test for continuity and polarity are carried out? If continuity is carried out for a light circuit then where the probes connect to? is it on the switch line and the cpc at the ceiling rose or the brown...

    Question regarding live polarity test. Please help.

    I am trying to carry out live polarity test to test correct polarity of the supply. The system is TN-S and single phase. My question is do i turn main switch off? Where on the main switch does the voltage indicator leads go? Is it on the top side of the main switch (Supply) or bottom (Feed)...

    polarity warning on IMO isolators

    The guy that works for me doing some of the electrical bits connected one of the new IMO isolators the other day. When I checked on commisioning the polarity was wrong. rather than connecting in a stright line through the isolator the connection goes accross, so the top left input is continuous...

    PV system Polarity

    I'm in a panic as assessment in 2 days. It appears I have the polarity wrong at the inverter this was corrected in the DC isolator and it's fine now however where should I correct it. I have used red and black cables so can I just use tape at the switch so the colours are right or do I need to...

    Which socket tester?

    Trying to decide which socket tester to buy, I like the Socket and See 32 / 34 /36. I already have a Megger 1553 which has RCD and Zs test. The highest model seems to detect E/N incorrect polarity is this only if the installation has an RCD?
