Laying new yard - consideration for future electric vehicles

    Hi,

    We are putting down a yard in parents new build house and I was going to put in an underground duct from garage (where the power enters the property) out to the yard wall in front of where the cars park for when in future that electric cars are mandated. The intent of this is to ensure that we don't have to dig up the yard in order to put a charging cable across or have cables trailing across the yard to the vehicles.

    It is not a big job at this stage to do. Is this all that would be required at this stage - was looking at a 4" duct - can't see the cabling being an issue in it.

    A 4" will make life much easier when pulling cables - put a rope in it now though, will make pulling a new cable much easier.

    It would be a 6mm2 armoured going to a charge point, (maybe 10mm2 if the run is very long)



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    Run at least two etnernet cables also alongside rope, cheap so no problem laying them now, or else you can pull via rope later.

    Beware of bend on 6mm cable if choosing armoured

    What are they needed for.



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    To communicate car charger with PV system and also for App usage



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    This will all be years down the line, so hopefully just putting in the duct will be sufficient at this point - its cheaper and easer to do it now rather than dig up the ground again. Although by that stage wireless charging will probably be all the rage anyway!

    Thanks - at least I know I'm on the right track putting in 4" smooth walled drainage pipe as a duct. That should prevent water accumulating in it too.

    How are these typically wired in the house - can they be connected via spur from an existing socket or do they require their own circuit from the consumer unit?

    Use the slow angle bend esb service duct where it exits to ensure future proofing.



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    I'm laying new frontway next week, have SWA ethernet and SWA 6sq ready to lay myself, also got a box steel pedestal to move charge point as we're currently doing Tetris given we've two EVs, will post pics



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    Thanks - we're just future proofing, so nothing to put into the ducting yet. What diameter is your ducting?

  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    No ducting, all cable Steel Armoured so no ducting required



  • Moderators, Society & Culture Moderators Posts: 40,346 Mod ✭✭✭✭Gumbo


    just to add, typically a 40a RCBO is required.

    The car will pull 32a from the house.



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    Would you not be better print it in ducting in case you want to change or alter things if it gets damaged? What sizes cables are going in again?



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    I already have a charge point so moving it to a more centred position as we are a two EV house, won't be moving ever again.

    As the cables are SWA there will be no damage, 6sq SWA for power and buriable CAT6 for comms



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    I put in 50mm inner diameter ducting. Should hopefully be enough.

    Thanks for all the advice.



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    Here's the cables, 6 sq SWA for charge point, 1.5 sq SWA for sensor lights and buriable CAT6




  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    And homemade stand for charge point, I just put something on back of piece of paper and local guy made it up




  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    Make sure to put up a finished photo!



  • Registered Users, Registered Users 2 Posts: 19,102 ✭✭✭✭Del2005


    There's regulations for burying electrical cable and I don't think your idea meets them. If doing it do it right, especially since you want to avoid digging up the yard.



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    18" with marker tape is all that is needed here.

    What charger do you have? Looks like a pretty elaborate stand

    Both of mine are currently attached to the wall in the side passage, it works but the cable is a slight stretch going to the far space

    We've rarely had to charge both EVs at the same time anyway but it's nice to have the capability if needed

    If I'm every getting the driveway dug up then I'll definitely be putting in ducting to bring the chargers out to the sides of the driveway

    where is here?

    555.6.8 from ET 101 2008 applies in Ireland, unless the new regs are different

    Zappi2, that's just the support I'm putting in, I'll be cladding it but want something that will last, if you're gonna do it then do it once!

    Re ducting, with SWA under directly poured concrete I'm not ducting



  • Registered Users, Registered Users 2 Posts: 12,417 ✭✭✭✭the_amazing_raisin


    Nice, I've a Zappi v2 as well. Agree that it you're going to put it on a stand then might as well make it look decent, since the charger is a bit of a chunky one anyway

    Armoured or not, I think it foolish not to duct if doing a concrete yard.

    You never know what can happen. If someone was to go in breaking concrete for some reason and destroyed your cable, you are fecked.



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    Won't be happening in my life time



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    I can only see the amendments to that doc. What are the regs you are talking about specifically?



  • Registered Users, Registered Users 2 Posts: 12,887 ✭✭✭✭Calahonda52


    I.S. 10101 replaced ET 101 2008 in late 2019 early 2020

    I can't see the regs for cables having been eased

    What were that that you remember?

  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    Buried down a good bit and whacked ready for pour



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    Pour was yesterday, new Boards resolution pretty crappy. I won't be doing anything for a few weeks until the concrete cures, I'm in no rush.

    Plan on making a "sleeve" to pop over this stand, isolator switch out the back (so not immediately visible) and charge point facing forward with motion sensor LED low down



  • Registered Users, Registered Users 2 Posts: 8,593 ✭✭✭funkey_monkey


    Does the control unit always have to go outside? I thought I had read about these units being stolen.

    Would there be a way to have the control unit secure inside and only the lead outside?



  • Moderators, Home & Garden Moderators Posts: 6,633 Mod ✭✭✭✭graememk


    you did read, but the poster was just taking the piss, and was actually getting his replaced



  • Moderators, Sports Moderators Posts: 19,477 Mod ✭✭✭✭slave1


    And after a short drying spell I've clad the support ahead of fitting charge point at the weekend. The rear is uncovered to allow cabling etc
