Hidden danger in service cut-out fuses - Phenolic degradation

[@dsbelectricaldavidbetterid8448]

Having the chap from dno back ground is a huge plus this is as like always a very good discussion.

In my decade as a meter reader, we never even looked at the cut out and were never told to. We did check for polarity though. Now as a meter changer we do note down every black phenolic cut out we see and check for surface voltage on them before pulling the fuse. Interesting that grey cut outs may have the same danger? That's the first time I've ever heard that.

As always, great content on this channel.

Wow. Between this and PEN failures. DNO's need to start changing legacy service heads and look at pulling in some new service cables.

old service heads dont fail that often it is usually false alarms

Awesome content Dave appreciate the info

Fascinating! Great podcast.

[@williammartinculleton5875]

Interesting indeed, thank you all , yes I had watched your previous video on phenolic degradation

[@shaunsparky5354]

Bearing in mind the argument of 'contamination', I am wondering how many people who carry their GRP ladders externally to the Van (ie roof racks) are likely to maintain such equipment?

😬

Could you guys recommend a suitable tester for testing between the MET and the black cutout fuse holder.

Having no issues, but when i had my tails replaced my energy supplier for a EV charged install, he advised a C17 and as i was having a 100A fuse upgraded he advised me to mention it to uk Power networks as could do at the same time, UK power networks booked only the 110A fuse and when i have queried about the C17 black plactic, and upgrading it, they dont seem bothered just advise that if the electrician that changed the 100A fuse saw any issues they would have mentioned it, so showld i push for this to be replaced or is it fine, they mention there are some customers with older metal boxes.
