    Leakage Clamp Meter Kyoritsu 2432 or Uni-T UT251

    I am considering a leakage clamp meter for use at my house. I am connected to the grid and have a separate solar setup. I live in Thailand where electrical installations aren't perfect. I have the feeling that one of the issues is leakage. So to further analyse I am considering a leakage clamp...

    Best earth leakage clamp meter

    Hi all I want to get a good and reliable earth leakage clamp meter, been looking at the megger DCM305E which looks good but was wondering what other peoples opinions are? I don’t mind spending the money on a good one rather than getting a cheap one and getting inaccurate readings or no longevity.

    5 amp earth leakage?

    Hi all Suggestions please. I’m working on a 3 phase shop install with a bunch of typical circuits. As each cct is energised the earth leakage rises to around 5 amps! It’s a PME supply via SWA with main earth coming from the armour. I’m pretty sure it’s not the individual ccts or appliances...

    leakage clamp meter accuracy

    hello. I'm using leakage clamp meter to investigate nuisance tripping in my house. It is a MULTICOMP PRO MP780050 that I bought early 2021. However, once I bought it the nuisance tripping stopped, so I put it down to damp in garage at the time. This looks just like the Dilog6518 (just without...

    Receiving 120VAC from frame of double insulated TV, is this normal?

    Got a jolt from the metal frame of my 2020 Sony KD-65X9000H TV. Measuring 120VAC at all times unit is plugged in. Now I know there's often some leakage with double insulated items but I thought that 120v seemed fairly high. Is that somewhere around the expected amount to leak? Contacted Sony...

    High leakage equipment?

    I have been asked to remove a 3 ph rcd from a vehicle entry gate, because they state it has an inverter power supply that can leak up to 160 ma . this does not seem correct to me and i wonder of the implications of having no rcd if this leakage is to earth on touchable large metal gates. any...

    extension leads - earth leakage

    Hi all, I can't understand why but I always get a small (minimum 0.06mA) earth leakage reading on extension leads (even without surge protection). Is this normal? If it is, please could someone explain how earth leakage occurs on a simple extension lead? Thanks

    Earth leakage

    Is there any guides on how much earth leakage is acceptable in an industrial setting ie MCC. The reason i ask is it seems to be most sites have a degree of leakage which I’m not sure is due to many VSDs being used but recently a panel I saw had 0.6amps leakage but the motor starter was all good...
