I had a look and it's actually a 13A fuse. I'll be changing this to 3A as the halogen floodlight that was out there has been replaced with a LED unit. Like said only want to plug a 240 to 6v IP camera transformer so overloading it will be very unlikely.
For the multimeter I will check tommorow. What happens if an appliance is run with the wrong polarity go bang or fail to work?
Thanks for everyone's help so far![]()
In that case I would simply install a single socket outlet and use 2.5mm.
A single socket outlet can only demand 13A MAX where-as a double can demand 19.5A (Getting way too close to what 2.5mm can safely carry for extended periods imo).
Saying ''only want to plug a 240 to 6v IP camera transformer so overloading it will be very unlikely'' is very dangerous logic!
What's not to say in a few years time a new owner discovers this socket and thinks hey ho, I'll just plug this high current device into this handy socket here
And/Or, damn this 3A fuse keeps blowing, I know what I'll chuck a 13A one in, ohhhh that seems to be working now

If your protecting a circuit by placing a 3A fuse where a 13A fuse can be physically replaced by an end user then that circuit is NOT safe imho!
You always have to take a belt and braces attitude with electrics and assume that the end user has zero knowledge of electrics.
On another note, that picture... Looks shoddy just from that little snippet![]()
Agree, no CPC sleeving and no doubling over on the cable terminations! Not very professional at all!
