Adding 32A Underground cable supply

[winston1]

Learnt some good things here guys .. appreciate it.
In case anybody wants to know …I will do all the physical install, but I have an electrician who will do an inspection & Part P certificate on this.
He is not too keen to dig a cable trench

This is prior to final connection to hot tub, which will be done by hot tub company when they install it.

No such thing as a Part P certificate. Part P is one sentence in the building regs, that’s all.

In this case the work will be fully inspected and part P certified by an electrician, I am DIY'ing the physical installation. My NICEIC electrician is happy to work this way.

No such thing as part P certification either.

The DNO could upgrade a TNS to TNCS which can cause issues.

I would personally regard that as a (cost-saving) 'downgrade' !
Edit: just seen EFLI's post ... great minds ....

Kind Regards, John

Loss of the incoming Neutral while the Live is still connected to the building can result in the "Earth" and CPC inside the building being pulled up to the Live potential via any load in the house between the Live and the Neutral conductors

If the supply-side fault is upstream of connections to other consumers' installations, it could result in CPCs within the building rising to a high potential (relative to true earth) even if the Live were not 'still connected'.
