Does model 30-442 P detect combustible gas?

It detects propane which is a combustible gas. Not sure if it detects any other types of gas.

does it shut the gas off

No, an alarm sounds to let you know there is a gas leak. It does not shut the gas off.

Ehat happens when detector is expired?

When it expires, it emits a piercing sound. It will continue to do this until it is replaced.

Does it come with lead wires already wired in? How long, what gauge? Thanks.

It comes with lead wires they are already wired in 4 or 5 inches long. I'm going to guess it's 16 gauge but that is only a guess hope this helps
