sorry, not sure what they are. Ottermill made Earth Leakage Circuit Breakers, used to make Voltage operated ones (now obsolete) Does the Ottermil thing look like a big brown switch?
Henley products are not often seen now, apart from a rectangular plastic box with two or more red, and two or more black, large round cables going into it. No switches or fuses on these, it is just a large junction box.
Can you give dimensions and colours of the things you have, and describe:
do they have switches on them? How many, how big
Do they have fuses in them? How many, what colour, what is printed on them
A "fuseboard" usually has two thick round cables (usually red and black, may be coated in grey plastic) going into it, and several flat grey or white cables coming out. Modern ones are usually white plastic. Old ones may be brown plastic. Very old ones may be wood or cast iron.
There should also be some green and yellow, or green, plastic coated earth cables, there shouldn't be (but sometimes are) bare steel or copper earth wires
All the cables should be sheathed in shiny PVC. If you have any that appear to be covered in rubber or cloth, maybe matt or perished, do not touch them but describe where they go.
About how old would you say the instalation is?
If you are able to take photos and email them to
