TJ Anderson thanks for response. My response you highlighted doesn't read well. I will try to explain better for discussion. That's what it is discussion not criticism.
When meter tails are over 3m an isolator is normally needed to satisfy the dno.
If the tails were split with say swa cable and a neat way was found to terminate the swa without the need of a fused switch then what is the difference between the new swa tails and the existing house tails? If they the same rating?
The difference the swa is actually better protected than the original tails that run for 15 meters through the house.
The discussion was if the new tails absolutely have to have a fused switch then why is just an isolator acceptable for every other property in the uk with meter tails over 3m.
I will be using a fused switch, I will be changing cable size to xlpe because of its increased rating I will be TTing the system.
The reason for the TT is its safer.
I can speck the install 100 percent because he doesnt know how many chargers he wants in the future. Most probably 2 but not ruled out more.
I hold my hands up to not knowing the true capabilities of xlpe cable over standard swa but I have now been educated
Discussion forum not criticism forum. People come on for help and advice in improving installs not to be picked apart otherwise what's the point.
Thank you. I apologise for my outrageous behaviour.
Absolutely......Let's continue our discussion.....
I am pleased to hear about your revelation regarding XLPE SWA. Amazing stuff it is. Can you educate me as to the equipment you are now designing to run at 90 Degrees Celsius? I have never got to do that in my limited electrical dabblings as I struggled to find suitable reasonably priced items for garages and garden shed installs etc
Why is TT safer here, we only have that PME at work. Am I in danger, I really don't understand??

Thankyou now that is what I call a well constructured reply. Explains the point very clearly and explains my question.
Again, I'm terribly sorry and I'd like to add the irony of this was not lost on me.
