Posted By Topic: Cable specs in new build

Hi,

I'm an owner builder and doing much of the leg work for my electrician, like pulling cable. He's unavailable at present and I would like to confirm that 1.5tps is acceptable spec for a rangehood and and bathroom extractor fans?

Also if mounted in a bathroom ceiling (2.4m high) can I place an extractor fan above a tile d wet area shower where the fan is at least 1200mm from the showerhead?

Many thanks!

as an unlicenced person who isn't a trainee, you're only allowed to do work either under supervision, or under the homeowner Exemption.

For "under supervision", your sparky can't supervise when he's not there, so you'll need to wait until you can talk to him and he can supervise you properly.

For the "homeowner side", everything has to be checked, certified, and connected by an inspector - so that's who you need to be talking to. You also have to be working to ECP 54, which is different in several ways from normal wiring rules.

Reading the EWRB supervision guide, it appears as though remote supervision is allowed if the person supervised is deemed competent for the task. However, I guess in this case he cant be remotely supervised if he cant get a hold of his supervisor.

Seeing as it's coming to the end of a long working week, you might find ECP51 more useful for the "homeowner exemption" rather than ECP54 for recessed luminaries. Although being the builder you might struggle to fit the criteria of "homeowner". as a house under construction wouldn't fit under residential either.

Got me on the ECP number - didn't take the time to check (never a good idea)..

But the "Homeowner exemption" can apply to house under construction, S 79 (checked that one) refers to "any premises that are occupied, or intended to be occupied, by that person as a residence for that person... "

As for competence; the questions asked clearly demonstrates that the OP is not competent to be selecting either cable size or location of heater; so "remote supervision" is not appropriate (not even remotely appropriate).

And asking a bunch of strangers to provide expert advice (for free) when they don't (can't) have all relevant facts isn't likely to end well.
