Hi All,
We have a project installing a 630A Panel board from an LV panel board within the same room. Due to space constraints we no longer think the 300mm SWA we were looking to install is going to be physically feasible. So we've been looking at running 300mm AWA's in Trefoil instead. It's a short run of around 13m & the panel board is going to contain a mixture of different loads.
We're obviously using the Aluminum glands & terminating into an Aluminum plate either end, however not having had to install cables in trefoil before - I'm not sure if there is anything else we need to be mindful about.
It's being installed on a 450mm ladder & I've checked within table 4C5 for spacing factors. I'm unsure if the neutral should be installed as close as possible to the trefoil? It's also been mentioned that Quad cleats are available to include the Neutral, Lastly it's been mentioned about potential single point bonding of the conductors - again something I've never had to do before.
I will be looking to get a design carried out, I just wondered if anyone had advice as it's not something we've had the need to carry out beforehand - So unsure whether there any pros / cons of doing this way as opposed to a standard 4 core SWA (Other than the physical impracticalities!)
Many thanks in advance.
Tim
