Hey Guys,
I just bought the Harbor Freight 2HP Dust Collector and so far just have it hooked to my Griz G0715P tablesaw. Will connect to Router table, Band saw, jointer…I am using a 50ft. 15 amp extension cord with a woods remote control setup. Do I lose any power by using the extension cord?

As always, thanks again for the good info…

Yes power is affected by using a long power cord. Alistair

Probably yes. Use a shorter extension cord if possible.

2% voltage drop at most, or 1% with a cord half that length. IMHO, that’s pretty insignificant.

(IMHO?) Ok so 2% voltage drop…right now it has a 5ft hose from the saw to the collector and will probably be 5 ft to the router table and 5 ft to bandsaw. If I were to move the dust collector closer to the outlet, I would have to increase my hoses to the machines…probably 10-15 ft each…wouldn’t I also lose suction there with the longer hoses?

Really in my experience you’re just more likely to blow your breaker with
the DC. If it runs, it runs.

Great, thanks fellas…Since a 2% voltage drop sounds pretty minimal, I think I’m going to try and roll with what I have instead of rearranging the shop…as always, thanks for the great feedback.

I had a small air compressor hooked up to a 50 ft extension cord a week ago and it just would not pull enough cutrrent to keep it running. I did trip the breaker eventually, but before that it just ran slower and heated up the cord.

The manual says not to use an extension cord. Having said that, I use mine with a 50 foot 12 gauge cord…

I would want a 12 gauge cord if possible but then again most of the receptacles in the U.S. are 15 amp. It would still be better than a 14 ga. cord. Amperage is lost in the cord and length is the enemy. It would also lose amperage if you wired it in hard and had a long run. A long run is a long run. You could just avoid some of the smaller receptacles. When I was working in the design business we supported equipment that would have a 240V motor running on a 208 service. That is voltage though.

make sure the cord is at least a 12 gauge or could you wire in a dedicated outlet for the DC, solid copper wire performs better that multistrand extension cords

The longer cord isn’t doing the motor any favors for long term reliability….shorter and heavier would be better.
