Default Gauge of wire.

Can you advise me on the correct gauge of wire please?

This is what Iím working with:

OO gauge track
Gaugemaster Prodigy Express
Layout L shaped 2.1m x 1.2m widest point
Running probably 3 locomotives max maybe 4 in time.

From what I have read I think I need:

BUS wires 32/0.2
Dropper wires 16/0.2

Am I right please?

Thank you

I used 32/02 for the bus and 16/0.2 for the droppers, some prices to think about....

2.5mm twin and earth
50mm £44.13
100mm £80.61

32/0.2 100mm requires 2 reels £18.47 each

Not sure if this includes VAT, source Rapid Electronics

There are smaller sizes of both types but the 32/0.2 is far better as its multi stranded....

Only use solid conductor wire on a layout that's fixed. Otherwise use flexible wire for the bus pair.
Your sizes in post #1 are spot on.
Sizes I recommend are.... Minimum for solid 1.5mm2 former mains lighting cable the inner insulated Brown and Blue wires removed from the outer grey sheath.
Minimum for flexible wire.. 32/0.2mm equipment wire or similar flexible wire.

For droppers rail to bus ... 16/0.2mm equipment wire and ideally in the same two colours as the bus pair.

Gosh your wire is expensive. In france, you cannot buy 3 core cable. They sell rolls of single sheathed cable, in 50 metre lengths, for £5.60. You buy 3, plus plastic sheath, and produce a cable. Hence my red and blue BUS, cost £11.20

Thanks for all the guidance and wise words. I have metres and metres of new 1.5mm solid core - brown and blue sheathed and bare earth all encased in grey plastic.

I think I will use the blue and brown solid 1.5mm squared (removed from the grey outer sheath). Then 16/0.2 for the dropper wires (blue and brown to avoid confusion) e.g. https://www.rapidonline.com/rapid-gw...2-wire-01-0910

Am I on the right lines now?

Thanks again for all the help.
