    Do I need a JB here? Will terminal blocks do?

    Long story short - I'm moving a light fitting. Previously it was a pendant with the loop-in in it, this new light fitting doesn't have enough blocks inside (common scenario it seems), plus I'm moving it about a foot. So I need to take care of the loop-in before coming off it to the light...

    Another socket puzzle: Why the extra terminal?

    Here's an old accessory made to BS1363. You can connect it to a ring and plug 13A plugs into it. What is the fourth terminal for? I've blanked off some text moulded into the bakelite so as not to give too many hints at first. Nothing else is hidden.
