Earth Electrode required??

[needsomeadvice]

Hi

I have been to see a job that has a TT system installed for the house. Dual RCD board in the house. All up to date.
I am looking to use a spare way in the house consumer unit to run some power to the garage. If i use a 3core SWA (one of the cores being the earth), do i need to install an earth electrode for the garage or will running from the existing board be ok?

Appreciate any help.
cheers

are you a spark ?

might be advantageous to add a second rod at the garage, might improve the Ra/Ze.

Use the existing if its ok, just check if its a metal board its got the 100ma type s upfront instead of the main switch as its TT, I've come across a few that havnt.

Given what you have told us probably not.
