Hi guys, 


I've got a few projects around the house I want to do:


1) Install new powerpoint in wall where the TV is setup


2) Install outdoor light


3) Install additional switch for laundry lights so switch is next to external door.


4) Install new powerpoint outside on deck.


Now before anyone jumps down my throat, I'm not going to hook it up to the switchboard myself, I'll get a registered sparky in for that, but what I can do is buy all the components myself and run the cable to avoid paying chump rates. I've already done similar to install two outside caravan power points on 6mm TPS. I just have a few questions regarding what cable I need.


So based on previous experience, I need 2.5mm TPS 2C+E for the powerpoints, I've been told I only need 1.5mm for the new light. Can I use the same 1.5mm for the additional switch?


I'm estimating I need about 50m of TPS 1.5mm for both lighting projects and another 50m of 2.5mm for the powerpoints. I'm trying to decide whether to just use 2.5mm for both and get a 100m roll.


Also people have told me to get flat TPS over circular TPS, but I found last time it was harder to run flat TPS because it keeps kinking, is there that much of a difference?


Finally the lighting diagrams I've been able to find show 3core + earth, is it 2C+E or 3C+E in NZ?


Thanks for the help!

Not Quite.


you have not interpreted this correctly.


Unlike any other person under supervision, a person subject to section 110 (Homeowners exemption)may do or assist in doing the following work ...


(e) Install, extend, and alter subcircuits (including submains), provided that–..




    (ii) The work is tested by a registered electrical inspector, ..




So if the homeowner is involved ( even assists ) in the installation, the work must be inspected.


This is why there is a tick box on the CoC that must be ticked if the homeowner does any work.. it results in an inspection being necessary
