The IET is carrying out some important updates between 17-30 April and all of our websites will be view only. For more information, read this Announcement
Over here in NI we often refer to the connector blocks for tails as ISCOs or perhaps ESCOs. I think Henley blocks are perhaps how they are referred to on the mainland. I used to know the words of the acronym but I cannot recall and a web search didnt help. Any ideas?
Here in southern England we only see ISCO on prewar cut outs and they are a dissappearing breed.
- I assumed it is a long defunct maker's name.
WT Henley has suffered many mergers but the name refuses to die out..

oddly that article refers to them making ISCOs, so it may have meant incoming service cut-out or similar for them - not a use I am familiar with

At least one DNO shares my view that it can be a maker's name, not a product description ;-) Saw this over the weekend. My blue underline.

Which is SPenergy networks current advice on deciding when it is safe to perform live swapping of cut-outs. (most of the time for single phase, if the cores cannot move around and do not touch it seems...though they do call for gloves visor and overalls, which is reassuring.)
