funny, been on a 2nd fix. 1st done by another. bloody tw4t had fixed all the boxes with the E terminal at top where i had to get down on knees to see it, manufacturer 's terminals so close in corner, hard to get wire in. tiny screws, 2 snapped off . 1 box i had to fit a ring lug to E wire and secure under fixing screw. pain in the arse.
Anyone ever thought of boxes complete with fly lead? failing that fit a fly lead during 1st fix.Hi,
What do you think of the earth screws that come on some metal Backboxes like this?

Compared to this type.

I prefer the type the second one because they feel easier and safer to work with.
and even worse when the terminal is askew and the hole to put your fly lead in is up against the metal box.The top ones can easily miss cores of cable and require multiple attempts to fix the core properly but they have greater capacity for cables if you have hundreds of wires coming into your back box. The lower ones are easier to fix but more difficult to see especially when installed as Tel says.
Did exactly that on a one off job that I'm doing. Crimped an insulated earth wire and fixed to earth terminal in box before fixing box into wall. did wonder why don't manufactures do it, but knew the answer straight away.....simple, down to cost!Anyone ever thought of boxes complete with fly lead? failing that fit a fly lead during 1st fix.
Six cables in one box bet that's a bit of a tight fit matetop ones better for me, i always have a lot of cables in my boxes, smaller one it 6 cables MAX.
bottem one better if only one cable in the box.
it's more important to take earth to the faceplate for sockets and for metal switch plates. earrthing the box is optional as long as it has 1 fixed lug.I have the second type boxes in my house. ... not that any of them are connected. Should they be? I'm only Level 1!
Where's these ones with 2 adjustable lugs then??it's more important to take earth to the faceplate for sockets and for metal switch plates. earrthing the box is optional as long as it has 1 fixed lug.
I hope you don't get any serious problemsSo you wouldn't recommend the screw type?
I need to pick up a couple of 35mm boxes and they all have screws. Which is going to make for a fiddly job.
