I thought I would add to this thread with a description of an installation I found last Saturday to see if anyone can better it
I hope I am not Hijacking this thread because the relevance is the sometimes over engineered current carrying capacity that we are fearful of not installing, such as the concerns about 6mm on large showers
It may put loading in a different perspective
A mate had his 100 m/amp stand alone Rcd tripping.
"Will I have a look"
Wylex 4-way (Lights Ring + ,Shower)
Neutral earth fault traced to
Double socket spur for cooker hood in extended kitchen
This double socket spur was feeding a total of 3 other double sockets which are being used for Washer. Tumble dryer,Fridge,Freezer,Microwave, ,Wylex 4-way in chicken shed 30 meters down the garden,External sun flood,cooker hood and lastly a Halogen cooker hob with a socket for an ignitor, which was jointed in the wall somewhere along the way all off a 30 amp 3036
I said "how have you managed to run that lot",his reply was,"we dont put the rings of the cooker on full,so as not to blow the fuse"
This is diversity arithmatic on another planet
The point I will make to tie it up with the thread is, given the enormous possibility of overload and fire with this install
The cable feeding the spur at the origin of this lot was untarnished,no melting insulation,no copper discolouring,nothing to suggest lack of current carrying capacity
The occasional blown fuse and the circuit worked like a good un
Slight overloading of a 6mm cable on a large rated shower, that is unlikely to run at maximum rating, and even then only for short duration is much less concerning than the install I desribed
