Hi all
Can "Conduit wire" be installed in "Square lid Clip on Duct" without additional protection (TPS vs single insulation)?
Just wondering if "Square lid Clip on Duct" and "Pipe Conduit" are considered the same level of protection.
I was always taught the use of a tool to access cables was required for single insulation.
Is clip-on duct lid classed as a tool level of protection?

Re: Duct vs Conduit
3.10.1 requires insulated unsheathed cables to be installed in a wiring enclosure (with some Exceptions).
That term is defined in 1.4.130.
The permitted types are listed in 3.10.2.1
The concept of needing to use a tool may be useful; but it is not a requirement;
or at least not a requirement of Wiring rules - it may be part of the relevant product Standards.
Which is all you have to worry about;
ie, is the enclosure you plan to use compliant with the relevant Standard?

Re: Duct vs Conduit
Thank you Alec
I hadn't thought about that. I trained in a time before standards (ECP's) and it's a different mindset.
When I was an apprentice I was told as a rule of thumb unsheathed cables need to be protected by an enclosure that required the use of a tool or key to access.
Using that mindset a lid that you can pull off without tools just seemed wrong.

Im using an older version of 3000:2007
3.10.2.1 (d) Talks about the use of tools

.....readily accessible position shall not be removed without the use of a tool
Re: Duct vs Conduit
Whoops; I should have seen that.
In fact, I should have known it
[In currently cited edition; it's para 2, not item (d) of para 1]
The "in readily accessible position" but is clear as to when it applies (ie not always);
But there could be difference of opinion as to whether a particular product needs use of a tool.
What sort of "Square lid Clip on Duct" are you thinking of?
All the plastic trunkings / mini-trunkings I know of; I would regard as needing a tool to begin removal of lid.
Most metal types also.
But I recall some metal types from my youth that had a lid held on only by being a tight-ish fit

Re: Duct vs Conduit
It was just the Marley Maxi or something like that.
The product has AS/NZS standard 5xxx can't remember the number, but that is good enough for me.
Overthinking the problem
I'm using a surface mount in a shed. I'm going from a "Meterboard" to "Switchboard" (they are really close) and I was wondering if I could use conduit wire through Duct.
Then I thought this can be opened without a tool and is this legal.
