That's the way I did all mine Shaun, but keep the iron 'tinned'!Cheers

I`ve done a lot of soldering droppers to track of many gauges and recently I`ve wired up a 7mm layout in my shed.
Soldering does`nt need to be a nightmare……..
droppers to track…………………………………………………………………………………………………………………….
a clean hot iron 25watt or 40 watt
a decent flux essential it should make the solder run immediately, if it does`nt it`s the wrong one.
don`t use cored flux solders.
A heat sink either side of where your soldering your dropper to reduce the damage to plastic sleepers.
two cheap paintbrushes. One for the flux. One to clean off the flux with water.
The result……..
The heat sink……. the best modellers right hand……… Hair clips……..
All you need to solder successfully……………………………………………………………….
The Green flux is similar to Bakers fluid and both are good for most modelling jobs.
The `sooty` pot on the lower left is a soldering iron tip cleaner/tinner and will keep your soldering tips at the ready forever………..
hope that helps

No one has or will criticise anything you do on here, but as you know, will always offer up hints from their own modelling experience in response to your questions. Always remember that there is rarely a definitive way to do anything, just choices to consider. Oh, and one should also bear in mind that advice seen here will usually be streets ahead of what is on You Tube! Personally, I usually take 'advice' seen on YT with a generous portion of salt!
Where opinions vary, just try them and see what works best for you. Job done, haha :)

I'm not familiar with rating wire by Amps - rather by diameter.
My droppers are 1.0 mm solid copper from the rail to just under the base board. Then stranded 1.0 mm multi-core copper to the bus, which is 2.5 mm stranded.
Considering that the DCC systems are typically rated at 5 Amps, it sounds like you have made a wise choice. :thumbs
Carry on - that man!

So at 15v you're safe for about 80 Amps…
1mm wire @ 240V is rated for about 10 A or 2400 watts (worst case buried in insulation)
at say 15V it should be able to take somewhere near a little less than 160 Amps so I think you're very safe there.
2.5mm wire @ 240V is rated at maybe 18 A or 4320W
so at 15 V you should be able to run 280 ish amps very very safe there
I know I've not allowed for the differences between AC and DC and frequency effects but at what we are going to run things it's near enough!!!

Hi Kevin,Hi All. Unless I have not seen the comment? It would seem that no one has criticised my choice of dropper wire,being 5 amp wire that has been stripped from "lighting cable", I expected comments like "I was being mean" and "why not buy new wire". that is meant to do a "proper job" and "it is cheap enough".. all the best. Kevin
Whatever works for you is correct.

More likely the correct wire 0.5mm flexible wire rated at 3 Amps@240V = 720W or 48A at 15V or to be really picky,
36A at 20V to allow for DCC going wrong and giving a full continuous voltage.
note IIRC most mains wires are actually rated at current * 250V but that is going a bit too deep for this.

You can get all correct dropper and bus wire you need from…………………..
expressmodels.co .uk
I also use their non soldering wiring kits……..
Although, if you used the non soldering `suitcase` clips` I would just get the wiring from express models and the clips from…….
farnell element14 UK……. because they are double bladed…….
I , absolutely, hate soldering wires under layouts …………
Cheers

I used to learn a lot from all the modelling mags in the 60`s, 70`s and 80`s
Nowadays, I learn most things on modelling forums such as this.
There`s nothing wrong with asking questions mate……

DCC Power bus lead. 3.3mm dia rated at 21A. Price is per meter.
EX/PBUS(A) Brown.
EX/PBUS(B) Blue.
Layout wire. o.2m dia. To connect to track. Price is per meter.
EX/PBUS(F) Brown
EX/PBUS(G) Blue.
Actually Kevin, I learnt about an easy way of wiring a layout for DCC from an Australian modeller called Olliead who did a YouTube blog…..
Cheers
