Wire for accessories

Quick question -

About to wire many accessories and some accessories are about 25-30 feet from the control panel/DCS AIU etc.

What would be the best gauge wire to use for that length. 18 or 20 stranded copper - especially for the accessories that are 30 feet away? Most are MTH accessories. Just want to be safe in the long run.

Typically, over runs that length, I usually use a large buss wire, like 14AWG, and then localize a drop of 16 or 18AWG.

That would definitely save me a lot of wiring individual accessories one by one.

What is the maximum size guage of wire that fits in the MTH AIU?
