Just stick the 63amp fused connector before the Henley block , or Lucy block as you call it, and your all good, as for your 2nd point, , the first part of the regulation is talking about the current carry capacity of the cable, in this case the meter tails, I'm pretty sure 25mm tails are...- Upton Sparks

Running a power cable from home siren to camera
unlikely to blow the fuse, the power requirements are low for both products, and as you said most alarms will allow for two sirens, the siren does draw more power when its in alarm mode. so if the camera does works then will it still work when the alarm is going off will be the question. the...- Upton Sparks

RCD Protection for submains
Yeah possibly but your have half a chance and your be compliment with the 18th edition . Personal I would look at replacing the sub main to an SWA. But that's a significant cost to the customer.- Upton Sparks

PE from metal back box to socket
I was also thinking of Reg 526.1 as well to why you should earth the back boxes with a lead. I don't believe the screw achieves that .... So your not confused, my position is; I'm with putting the fly lead in, I think that is the right way. I am also on the opinion the back boxes is an...- Upton Sparks

PE from metal back box to socket
Apologies for the late arrival to the conversation, So, does anyone know where in the regulations (BS7671) it says, you can use the lug hole of the metal box as an earthing point? I think the regulation 411.3.1.1 applies, As does 132.1 The only question is. Are the metal back boxes classed...- Upton Sparks

If that is the main earthing conductor, then you have a problem and would need to call out the national Grids local sub contractor to your area ( possibly UKPN)to look at fixing a new earthing point to the SWA of the Sub main cable. They will...- Upton Sparks

To re-wire? Or not to re-wire?
No. Professional Sparks job's are to make sure the installation is safe. The selling of your services are completely unrelated to the issuing of certificates, but I do see EICR as a sale tool, because they are.. That does not mean you scare people in to having work done which is not required...- Upton Sparks

To re-wire? Or not to re-wire?
Ebola hey ? I think you've got the Idea, sell them a rewire. by the way, FI on a EICR should result in an unsatisfactory certificate. FI are not a get out of jail card. Its not your goal to issue satisfactory certificates, it should be to access the installation and to make sure the...- Upton Sparks
