    Making up industrial test adaptors - fusing leads?

    I make my own ceeform adaptor leads for testing purposes where the 4mm banana leads generally just get plugged into my own MFT which is all internally fused. All ratings and sizes - 16/1 up to 125/3 However, it's occurred to me that technically that's not compliant to GS38 (or certainly not in...

    Fusing bathroom timer fans

    Hi all, happy Christmas! There was a thread on this subject a while back, not many people said that they actually connect bathroom extractor via a 3A fuse, despite many MI's seemingly asking for it. And certainly it's not something you see often, triple pole isolators yes, sfs's less so. Is it...

    Hager meter kit fusing stupidity

    Today we got our Hager meter kit for one of their 125A TPN boards. It has a little DIN rail fuse holder as the meter is powered right off the incoming isolator/RCD/etc without any MCB for protection (so the meter can't be switched off without everything going off, presumably so you don't cheat...

    BS 1361 50A ZS

    Anyone know the ZS for an 1361 or BS 88-3 50A fuse. All the tables I find have n/a. I phoned the maker and was told there are no listed ZS' for a 50A and to take the difference between the next closest sizes (45A & 60), surley thats not proportional ?

    Hi all, Most manufacturers state that their extract fans need to be fused down to 3A. I don't know many sparks that actually do this, however I did on my last one. I'm looking at doing this again but a different method. Has anyone ever fitted an in - line fuse holder with a 3A fuse in the...
