the ones i did didnt need the condensation drains or test points i suppose it depends on the site environment, testing was done at the various points we drilled, after all this is where any smoke is detected. i have edited the earlier post because of the hole size, the system i installed was...

have installed similar systems a couple of times, it is as simple as that - put your sticky markers on where you want a detection point, drill 2-3mm hole. make sure all joints are securely glued and you have an end stop on the end of your run. another thing to watch is that the area is dust free...

i agree with that chris but on the test sheet it asks for max zs permitted by bs7671 and there isnt a table to back this up on circuits over 32A on a TT system

i'm not saying there was a problem, just asking where the table is table 41.3 " maximum earth fault loop impedance for circuit-breakers with Uo of 230v, for instantaneous operation giving compliance with the 0.4s disconnection time of Regulation 411.3.2.2 (the maximum disconnection time stated...
