How to prepare conduit for electrician to add power to my patio?

[Simmywoo]

Hi, 

im in WA, I’m building a free standing “patio” in the pool area, and I want to get power to it.

I will need a couple of gpo’s a fan and a couple of lights, overall dimensions are 5mx 4m x 3m high sloping to 2.5m (scallion roof). Between the house and the patio is a deck, I have removed a couple of decking boards and dug a trench from the house to one of the holes that will have one of the uprights (100 x 100 x 5mm galv post). What I need to know is what to put into the trench/hole to allow my sparky to run power from the house (cooker socket) through the external wall, into the trench and up to the upright…..ie, pvc pipe/metal conduit?, is there a specific product that needs to be in there to conform to WA protocol?, or does it just need to be a certain diameter so they can push through what they need?

also do you think this will be able to be just wired in addition to the ring main I already have, or will need seperate wiring back to the switchboard with its own breaker?……apologies for the mega long query.

Hi @Simmywoo,

A warm welcome to the Bunnings Workshop community, it is fantastic to have you with us.

Unfortunately, this is a question best asked of your electrician. They will be able to tell you the type, quantity and depth that the conduit needs to be buried to ensure that you comply with the relevant Australian Standards.

This will ensure your electrician is happy with what you've done, and everything is installed to standard.

Let me know if you have any further questions.
