    Does anyone use the UNI-T 528 test tool

    I'm wondering if anyone has used this tool. First of all I'm an automotive electrician but my work sent me on a PAT testing course and we have a DeltaPAT mi3309BT unit at work. I was thinking of buying something cheaper like this tool just to experiment with at home. I am 8 years away from...

    My EICR test guy says I need to change my bathroom ceiling light to an IP65 rated.

    My EICR test guy says I need to change my bathroom ceiling light to an IP65 rated. Research says I need an IP44. The lamp is about 2.45m above the floor and about 30cms outside the side of the bath. Has he made a mistake or have I?

    Battery tester that test batteries under load

    I am confused about battery testers for house hold batteries, AA, AAA, 9V, etc. Recently my smoke alarms started chirping so I changed the 9V batteries and no chirping.
