    Need to wire a supply to combi with LNE connections, and 2 volt free cores for room stat.
    I don't really see why I can't use 5 core flex for this, as all cores insulated to 500v, but plumber insisting they need to be in separate flexes...any thoughts?

    Cheers

    Wonder why they make 5 core boiler flex if it’s not allowed?

    Some manufacturers instructions......can’t remember off the top of my head though, state a separate cable should be used for the volt 3 connections.

    Cheers,

    This is a Worcester. Will get him to check mi tomorrow and see if this is what he's on about...annoying if I need to run in a second flex though!

    Out of interest what Worcester? I haven’t touched one for a little while now, but I’ve never come across a Worcester with a volt free connection.

    I would do it in 5 core but to keep wet pants happy just do in two flexes next he'll be moaning regarding the gas bonding not being at the external meter. Have you already put the flex in?

    Interesting....I haven't seen it yet....but that is the spec I was told...Will get details tomorrow on model and mi and get to the bottom of it. I suspect plumber has got wrong end of stick, all I know so far is that it is an older model that is being relocated.

    I’m doing 2/3 Worcester’s a week at the moment and none of the current models need a volt free roomstat, they are all 240V for standard controls.

    I wonder if the water clown is getting this confused with using the Ls terminal to supply external controls.
