I am continuing my practising today and am trying to get 2 x 2.5mm into oval conduit. It's not as easy as I thought it would be.
First of all I used some old cable that I had all twisted up ready to be scrapped. No way was this going to go through either the 20mm or the 25mm conduit.
I then tried some new cable so that it wasn't all bent up. This went in fairly well to both 20mm and 25mm, no real difference, but it did take some force at one or 2 points to get it through a 2m length. The whole idea is for me to speed up on a rewire, so I'm just looking for tips for getting the cable through the conduit?
1. Lubrication?
2. 20mm or 25mm?
3. Completely unbent cable?
4. Do different manufacturers have oval conduits with different internal dimensions, or are they pretty much the same?
5. Both cables in at the same time, or one at a time?
Also, I can see how oval conduit helps speed things up if you have one or 2 cables in the drop, but what if it's 3+ cables? Do you then just use a second piece of conduit, larger conduit or go back to capping? If you use a second piece of conduit isn't that going to take longer than one piece of capping?
Wouldn't a piece of trunking be a good idea in a chase? Easy and quick to screw into the chase with concrete screws and you can use 32x16mm trunking if you have lots of cables?
Cheers guys. Back to work on Thursday, so all my practise threads will stop then! ?
