braided wire or solid for 24 volt


My sprinkler system calls for 18 guage wire to run the 24 volt solenoid valves. They say to use "direct burial" wire. Before I go to the hardware store and hum and haw......should I be looking for braided copper or solid copper wire?

I''m a little worried that nobody will know at the store.

Doesn't matter whether you use braided (stranded) wire or solid wire.

Except if a section of wire is subject to flexing (not a problem with buried wires) braided is better.

Get sprinkler wire. It's special. It usually comes in four or six circuits (5 or 7 conductors) and has color coded conductors for easy identification and a direct-burial-rated jacket. You can also get single-conductor sprinkler wire. It's very heady duty for abrasion resistance. Using non-sprinkler direct burial cable will be unnecessarily expensive because the only other common type of direct burial cable is UF, which is rated for line voltage and thus more expensive.
