   If the saw and the dust collector are cord-and-plug connected, with either 15 or 20 amp plugs, then runing them off of a 30-amp circuit is a violation of the National Electrical Code; the circuit ampacity has to match the rating of the receptacle and the plug.  That means a 30 amp circuit can have only 30 amp rated receptacles and plugs on it.

   The one exception is that a 20 amp circuit can have two or more 15 amp receptaces on it.

   Get a qualified electrician or electrical contractor.  If you're really in the fire service, you know that poorly done house wiring is a significant cause of house fires, and shocks and electrocutions.  And just because some wiring works, doesn't mean that it's safe.

   The plug on the saw is rates at 80 Amps; the outlet is rated at 30 Amps. The dust collector will be hard wired with an appropriately rated switch. It will get an inspection.

   Glad to hear that you have things squared away.

   Merry Christmas and A Happy New Year.

   An electrician friend who taught me a lot allways told me to stay at or under 80% of the rating and you should be fine. At 30 amps that gives you 24 with no problem. As others have said you need to stay at a minimum plug and cable to match the breaker, which you said you had, so no problems.  You could even get one of those remotes that senses power is on, and automaticall cuts on the dust collector.  I love cool technology, but I'll have to stay with the remote on the key fob.  Take care and enjoy the saw.

   The load on the circuit is fine for installing both tools to the same circuit. Because this is a cord and plug application, you do not need to derate the circuit for 125% load.

   Technically Cliff is correct that you cannot put a 15 or 20 amp outlet onto a 30 amp circuit (nor can you use a 40-amp outlet). However, the risk isn't that the outlet device won't handle the 30 amps, but as an identification that it is a 30 amp circuit.

   This is deninately a case of do what I say, not what I do, Because I have several 20-amp twist locks on 30-amp circuits. (I would never do this with the flimsy 120 volt outlets though.) You would not pass an electrical inspection now, nor a home inspection when you went to sell your house, but given your specific conditions, I think a fire marshall can properly assess the risks.

   You should be fine unless the DC is full or the saw blade is having a hard time cutting. You don't want the breaker to pop while cutting.

   If it was mine, I would supply them separately but that's just me.
