Have the rules changed ?? Assess the maximum demand of the installation, if this does not exceed 60 Amps then 16mm tails are acceptable. I think NICEIC inspector told me this. Make a note on the certificate. It's important that any additions to the connected load do not exceed the rating of the...
Not sure what reg I would quote, I am thinking with my NICEIC hat on, just cover your arse. The regs can be interpreted in lots of ways but sometimes common sense has to prevail. The 17th edition stated that equipment must be suitable for the location, that's why you can't have a light switch...
Is the circuit protected by a 30mA RCD ? If the answer is yes then the results are pretty un-inportant. Maximum Zs is 1666 ohms. In practise a reading over 200 ohms woukd be considered unstable. Sorry if I've confused things. By the way if it has no 30mA RCD protection then that would be more of...
Forget the regs it's lethal. The distances in the regs are for a fixed shower head not one you could wash the whole room down with. I would give it a C1
How is the 4mm run to where it splits ? Apply a few de-rating factors and your 4mm becomes a 20 Amp circuit. Nothing wrong with the circuit arrangement by the way.
They haven't used the second RCD. Does not minimise disruption in the event of a single fault. The original post says they were asked for their NIC number, if they are claiming to be registered and are not, NIC will prosecute them. One of the few things they are good at !!
Use Ashley J803 0r 804. Bin the connectors inside and replace with insulated through crimps. Complies with regs. Maintenence free, cables secured against strain at their terminations, non flame propogating enclosure. However I only use this method if it's really hard to rewire. Rewire is the...
r1 + r2 is als
I stand corrected (well sit down corrected to be precise)
o measured for initial verification. Ze + (r1 +r2) is approximately equal to the expected Zs. Ensures that the circuit is safe to energise before "live" Zs reading is taken. Apparantly is acceptable to calculate r1 + r2...
