Hi All,
in our new house we had planned to have all our dgpos at 150/200afl so that they don't clash with bed frames (@200afl) or other furniture when we push these against the wall. However, we've just learned from our builder that that's not possible as 'the drill is not long enough', and we need to have the dgpos at 300afl.
This doesn't make sense as the only distance that increases by going from 300 to 120 is the distance to the ceiling, and I don't think they drill down from the ceiling with a single drill bit. So I'm not quite sure why the drill length matters when changing the height of a dgpo. Or is it rather the cut-out for the conduit that can't go that low?
Could someone please enlighten me what the situation is? Is there a legal requirement on the height of the dgpo? Or is there a technical limitation to how low the dgpo can be positioned? It would be good to know all the background before I start arguing with the builder.
Thanks for any help,
Tom
PS: The exact wording is: "All dgpo's must remain @300 afl or higher due to maximum length drill can reach through brickwork"
