I have always used TT System for pool installation but I can not find anything that states this to be a requirement. I know why but where is it in writing please.:confused:
 
isnt it something to do with the fact that you may introduce a potential from earth to the MET of the installation if you were to use TNC-S, or TNS. TT is good practice IMO, especially withnthe body having greatly reduced impedance when wet
