    Here is a job I've got to put in soon. I don't have the exact lengths but the edging on the bed is approx 70ft just to put it into perspective.

    I know the hub method is usually preferable. I this case I wonder if a T would be more practical.

    BTW, this is my first install. I went to a seminar last year. Im going to another next week. I'd like to get some of the wire pulled before then. I have to go under a sidewalk(sleeved) and the TF is going next to the pool equipment so I have to mount conduit for that as well.

    Hub. Pull a home run/Hub to the middle of the last 4 lights. Hub in the middle of the 2 red and 2 blue lights on the corner. and a hub in the middle of the first 4 lights. Done, no need for a T where you will have to make 2 times the ammount of connections. Assuming you will use fixtures that have 25ft leads you will only be making 3 connections. If you are using 20 watts or less you could probably make larger and fewer Hubs assuming your distances were not to far.

    when you say "...and hub in the middle of the first 4 lights"

    I want to make sure here. Do one home run to the TF as mentioned.

    Then for the first for light will hub together and home run back to the first main hub?

    no wait I misread.....forget all that

    bingo and dig 1 main artery trench to hide most of your wires in with an irrigation shovel then slit trenches to the fixtures from the hubs.

    each hub has a homerun to the trans. but you can simplify this by putting them all in line with eachother so there is one trench to dig. follow the lighting curve and dig a main trench. Put any leads you can in the trech and your 3 mains.

    Sorry this is the only pic I have of what Im talking about. We dug along the curb to put in all the mains and homeruns. We were also able to put in the fixture leads into the same trench and since it was soft sand it was real easy to get plenty deep. After we backfilled and pulled the mulch back you could not even tell we had been there.

    Okay heres what I have. It doesn't lllustrate the trench path but just the hub config.

    thanks guys. again that whay I can pull the wire and wait until I go to seminar on the 16th. I think a refresher will do me good.

    you got it! remember to try and route wires out of harms way. and Protect them and make them extra deep at any bed edges or places a lawn edger will be run.

    TPnTX, Thats the ticket! Like Billy said run all the wire together where you can. The green line looks like a good spot to dig it in as it looks to furthest from planting and edging. Who's seminar are you going too?

    Billy, Did you bring that dumpster to the job with you? :) Looks like a nice shack...any more pics? Thanks!

    You got it. Like billy said run all wires in one trench. You should alway burry your wires along an edge as for ease of remembering where they are and also so the homeowner knows that if they ever re plant they will knwo where the wires are as to not cut them.
