I have searched around the web and here and haven’t really found a solid answer to this. Is anyone using a HF DC with a Thien separator and canister to power tablesaw collection with a split 4” to the cabinet and 2 inch to a overarm unit? Currently, I use the DC to the cabinet and a shop vac to the overarm. It works great except I trip breakers. I am planning a more permanent DC solution with a separator and solid ducting soon, as well as looking into new electrical. Currently I just can’t avoid running it all on the same circuit. Clearly that doesn’t work.

I guess the question is, does the HF DC have enough juice to power both a cabinet and overarm duct at the same time? I was assuming I would do this to save from having to use the shop vac as well, but now I wonder if it’s worth it. I saw some comments somewhere recently that the HF DC, even with a canister, just doesn’t have the power to run both those runs with any effectiveness. If I just CAN’T afford to upgrade anything right now, am I better off just going with a 4” to the overarm and forgetting the cabinet run for now?

Using a R4512 saw, so I can go back to just emptying the cabinet when necessary.

I would think the bigger problem isn’t the DC, but the 2” hose going to the overarm pickup. DC’s and 2” hoses (as a rule) don’t get along to well. If you stay with that 2”, I’d also stay with the shop vac, they are made to work with a small hose.

Fair enough. So what is my best case scenario? Skip the cabinet collection and go with 4” to the overarm? I just can’t get enough consistent power draw to run the DC, Saw AND shopvac all at once. I seem to have had better “visual” collection with running just the overarm. If at some point in the future I can get electrical re-done maybe I can add back the shopvac portion. But there can’t be no-one using a Wye connection to power both cabinet and overarm on one run. I would assume with the HF unit there is no way it would sufficiently power a double 4” Wye, would it?

Try it and see. The problem with giving a DC opinion is that everyone has a different expectation of performance. So to see if YOU’RE happy with it hook it up with some temporary setup and see what happens, it may be just what you want. I can understand the electrical problem, until that’s resolved you may have to choose between one or the other (overarm versus cabinet).

Yes, I have a problem with over-planning/thinking. I have the components to try it with a flex hose instead of permanent ducts. Just trying to plan for the future. If it works ok with flex, it should be even better with smooth pvc.
