June 1Jun 1 I have been putting in foul drainage this week and now need to put the conduit in for the 2 * 23 KVa cables that will come under the lintels and into the plant room. I do have a 54mm diameter hockey stick and was wondering whether to just put two of those in, or am I better off using another type of conduit? Thanks

Thanks Ok, so we need cable sizes, eg outside diameter, to comment. What are these cables for?

June 1Jun 1 I brought 63/50mm flexible conduit into the house from the garage recently. Inside that is a 16mm² SWA along with two 20mm flexible conduits for data etc. With hindsight I should have gone for 100mm especially as I'm now considering another EV charger. I was mind (still am) tight for money so the 63/50mm came off FB marketplace cheap. Ah well!
June 2Jun 2 Author With regards to the 100mm ducting. Do you simply just put a bend in it or do you buy a preformed smooth bore bend? If such a thing exists.
June 2Jun 2 Where we are, if you don't have the right ducting the DNO (UKPN) won't run the cable. They will tell you what they need. Just re read and I see this is your side of the meter, so 100mm rigid duct will be OK. Edited June 2Jun 2 by Mr Punter

Just observe a reasonable bending radius and it’ll be fine. Stopping and starting with fittings causes a snag, so one continuous piece, joints in a perfectly straight section only, if needed, and get a 6mm nylon draw rope in it when you lay it.
