Hi guys I was wondering if someone can give me some help using the bus and droppers wiring system for my new plan.

I'm struggling where to isolate and put power feeds for the layout

Below is the plan I have and I'm wondering if someone could help me please.

Ok so another thing I'm not exactly sure of if I run a bus wire do the 2 ends of each wire i.e. + and - do they connect together to form a loop before going to my powercab system? Or does the end of the + and - wire end just before it meets up with the start of the wiring ?

Thanks for the replies guys. I'm still a little in the dark what you mean by a t shape though Richard. I just can't picture what you are meaning in my head. A diagram would be helpfull in what you mean though.

The system I am using lancashire is the nce powercab system to power the layout.

Looking at a previous diagram that Brian did for me for my last attempt at a dcc layout shows me where to place the powerfeeds and also where to place the isolating sections. I have included below the drawing that brian did for my last layout which was easy enough to understand for a sticko like me.

Sorry but I forgot to mention as well that it is kato track for the majority of the new layout with some peco flexitrack for the sidings lines.

So with regards to the isolating joiners where would I put each of them then to stop any chance of an overload or is there no need for them?

yeah that's right richard and also with me using Kato unitrack the points have directional power according to the website that sells them at least.

"All points are self-isolating (Just like Peco), #4 points (#20-220/221) also have full power routing capability." And these are the points that I have.

Ok so before I take the plunge and place my dropper wires to the tracks so then all I need to do is get my bus wire to connect them to. I have done a diagram for where I think I need to place the isolated joiners and also where to wire the dropper wires to.

Please could someone take a look and see if I have got everything covered and tell me if I am going to run into any problems.

Just to cover the basics again.

I'm using the nce powerpro system. The track is Kato Unitrack and the points are self isolating with auto power routing on them.

I have also included the key to the left of the layout to explain what everything stands for as well.

Ok so the droppers and isolating sections are now in place.

Started at 11.30am this morning and just finished at 16.35pm.

So just have to wait to get the main bus wires hopefully on Friday and then hopefully I should be up and running assuming that I have done everything right.

I have checked checked and checked 2 more times to make sure I have covered everything so there isn't anything I have missed. (trust me to say that I probably have overlooked something now I have said I have checked everything something is bound to go slightly wrong but that's all the fun of this hobby.)

right I've had my first testing of at least 1 line on the layout and apart from a little light cleaning of the track it went very well. I only connected up one of the droppers to the nce system just to test the middle line and am really chuffed with myself as it actually works...lol.

Thanks to all who have helped me so far and I look forward to fitting the bus wires and then having the whole layout to run around on.

Just out of curiosity about the bus wire Richard I have been told that if I don't get the right gauge wire for the main bus wire I could suffer some kind of electrical problem. Now I'm using 7/0.2 wire for the droppers from the tracks and I have taken on board what you have said about what wire I need for the 32/0.2 wire for the bus wire should I have any problems using those 2 kinds of wire together?

ok thanks for that Richard.

For connecting the droppers to the main bus would you recommend wrapping the dropper wires round the main bus wire and then soldering them together or just wrap the droppers onto the bus wire and then wrap it in tape just in case there is a problem later

Well I spoke to Maplins on the retail park which is a massive store and they said they would have to order in the 32/0.2 cable on a reel so that I can get the length I need without cutting. I phoned the maplins in middlesbrough today which is a much smaller store but has been there for years since I was a kid and they have all the reels of the stuff I'm going to need and for both the red and black wire I want they have quoted me £20.50 for 15 meters of both colours in total which I think is pretty good. I will ask them when I go get the wire tomorrow about the connectors you guys are talking about but from previous experiance I am going to strip the area where the droppers are going to go then solder the wires in place and then I'm going to cover the joints in electrical tape so that the bare wires are covered properly.

So by the end of the weekend I should have all wires powered and up and running. Woohoo....

Thanks for the link Tony but I have already looked at that one and it works out more expensive by about 3 or 4 pounds and that is even without the postage. It's only a 5 mins drive to the Maplins that has the wire I require so that has pretty much swayed my decision really.

Ok so I went and got the wire I need for the bus wire when I was out this morning on the way to the docs for a checkup.

I didn't get a chance to do it today but I will try and get it done tomorrow after I return to from the Hartlepool model show.

well I was going to wire the bus wires to my layout today but due to some discomfort caused by an unknown entity I am finding it hard to stand up for any length of time so it seems as if it is going to have to wait for another day at least until the pain calms down a bit.

Ok so now I am semi well again after my pulled muscle I decided once i had woken from my nightshift to have a go at 90% finishing off my wiring of the layout.

Everything went well putting the bus wires to the board and also connecting the dropper wires to it as well.

And I can confirm that after a slight little oversight by myself ( accidently connecting 1 set of droppers to the wrong polarity) that the layout is now up and running apart from the depot/sidings area. All the passing loops work well and I am pleased to announce I am finally the proud owner of a working 3 running line layout.

Thanks to everyone who has helped me in the wiring of this layout as I couldn't have done it without your help. Now for the unenviable task of doing the backboards surrounds and scenic design.

Yeah well I had some slight issues with dirty track seeing as I didn't clean it from removing it from the old layout but once I get things settled I'm going to send round my atlas track cleaner behind the drs loco I know works round the track.

I will get some pictures online sometime tomorrow as I'm jiggered after being in the shed doing the wiring for nearly 7 hours and seeing as I only went to bed at 7am this morning after working a nightshift and I woke up at midday and then basically started on the wiring straight away. My back is killing me.lol.

Just need to replace the kato straight sections with peco flexi track now and also put the dropper wires down for those 3 lines now and I am done. I thought just getting the 3 running lines working first along with the passing loops would suffice for today.
