    Class 1 Earth Continuity for PAT test.

    Hi guys, When performing an earth continuity test on class 1 appliances can you get away with just using a 200mA current on every piece of equipment? Having been on the 2377 course they say to use 1.5 times the fuse rating upto 26A for non IT. Need clarification as to what is right...

    Hi all Just got a metrel mi3000. Was using it today to test a new cu job. But I'm confused...when I do continuity tests on a ring I can do tests on the crossed line and neutral using the plug adaptor but I can't use the plug adapter to do test on crossed earth and line!? This means I have to...

    75 volts on earth

    Hi all , was doing a periodic on a domestic board. First I got 75V between the main earth and bonding earth . There was a L/E fault after clearing the fault I've tested between earths and now getting 8V. Is that acceptable , or is it still a fail . Thanx in advance.

    Main Protective Conductors - Continuity and Connection Verified - Sighting Clamp

    Are there any circumstances when it might be acceptable to tick the "Continuity and Connection Verified" box of the Electrical Installation Certificate when there is no visual or physical access to the point at which the bonding (normally a clamp in domestic) is applied. If so what checks over...

    Continuity testing

    To do a R1+R2 test you connect the Line and Cpc together and test at the furthest point. But on the test sheet I have there is also a box for just an R2 test aswell, how do you correctly do just an R2 test?

    Earth Continuity Test - Current Through Probe?

    I noticed some sparking coming off the probe during earth continuity tests on class 1 devices when the probe is touched to the metal casing. I placed a clamp meter over the probe and got readings of up to 10 amps. I can also feel a vibration from the probe lead during the earth c test. It's...

    What exactly is required to calibrate a voltage continuity tester?

    My company does not allow us to use our own voltage/continuity testers. Instead we must use the ones they provide for us. They're pretty cheap but do the job well enough. I have had my testers for just over a year and the label says that I shouldn't use them after that time so I handed them...

    continuity on ring main

    Hi. be nice for some feed back on this. I'm testing a ring main for an eicr. I know that the cpc reading should be around the 1.6 times higher than the live conductors but I'm getting 0.66 on live, 0.67 on neutral and 0.61 on cpc. I'm wondering, if the cpc are connected through the metal k.o box...

    Concealed bonding conductors

    Morning all. I'm about to set off to a cellar conversion. The gas, water and electric incomers are all in opposite corners of the cellar. In the next few days it's all going to be plasterboarded, which will conceal the bonding conductors permanently, although the actual earth clamps (i.e. the...
