Got my Delta 1.5 hp DC up and running, Two problems though
1 the bracket that holds the pole that holds the upper bag has already broken, Cant believe the poor craftsmanship, Expected more from a delta tool.
2 More importantly, When i turn this thing on the lights in the house go dim for a few seconds, Is this common and how do i make the wife not think i am going to blow the place up.

You should have a two year warranty- Delta should make good on the bracket. You can try calling Delta (1-800-223-7278), have your model and serial #'s handy. Don't know which 1.5 hp collector you have (50-850, 50-850A, 50-760) but as to the dimming lights I've found my 50-850 to be pretty marginal on a 15 amp circuit- it would pop the breaker time to time and I suspect the 50-760 would be the same. On a 20 amp circuit I've not had any problems and don't think you would either provided you don't have big amp draw items on the same circuit. The 50-850 can be rewired for 220v and iirc the 50-760 can too.
how do i make the wife not think i am going to blow the place up. ..
I'd tell her you know I do not hear you well and I invented a circuit to let me know it was running!

You won't blow the place up, but the dimming suggests that the circuit you are using is undersized for the load you are placing on it. The DC should ideally have its own circuit.
If the DC isn't on the same circuit as the lights that are dimming it would suggest that your wiring is probably inadequate throughout the house or there is some problem with the breaker panel installation.

I second what John said. A 15A motor should be on a dedicated 20A circuit. Its not the tool's fault if lights on other circuits are dimming significantly or for any period of time after startup. Andy
Not that I disagree with putting a 15A motor on a 20A circuit, but 1.5 HP motor is not a 15 amp motor. It's closer to 10 amps, though it would draw more on startup.
T, I thought the question was about a 1.5HP DC like the Delta 50-760. That has a TEFC motor rated at 15A. Should be on a 20A circuit based both on the fact that motors can deliver slightly more than their continuous HP and the safety margin in the electrical code. If you think that a motor only draws 10A while delivering 1.5HP, you forgot PF and efficiency in your basic ohm's law calculation. A 1.5HP motor draws close to 15A or more. A motor rated 1.5HP and 10A is probably overrated. If you measured the current draw of your 1.5HP DC at 10A, try measuring when it gets clogged. Btw, starting current is several times FLC. That may be why regulations and general practise have larger motors in your house on separate circuits (fridge, washer, AC, woodworking tools). Thanks for playing though. Andy
"but 1.5 HP motor is not a 15 amp motor. It's closer to 10 amps...." I have two 1.5HP motors in my shop, both Jets and the motor plates read 18 amps for one (table saw) and 11 amps for the other (dust collector)
"though it would draw more on startup." Bingo. And start-up was the original focus of the OP's post, IIRC.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
"If the DC isn't on the same circuit as the lights that are dimming it would suggest that your wiring is probably inadequate throughout the house or there is some problem with the breaker panel installation." John, I'm not sure an electrician would agree that dimming is bad, period. [Although, the desicription of the OP as to dimming sounds very much like the circuit is inadequate.] Back to my statement though: We're in the process of having a bunch of wiring done in my shop, and while the electrician was here, he examined both the main panel and the subpanel, and I asked all kinds of questions, one of which was "The lights dim in the house (just a bit, not a bunch like our guy in this thread) when I turn on the table saw, or even the vacuum in the house? Does this mean we have wiring problems, or whatever."
The answer was "No." Some dimming was not an issue, according to him, and he's a second-generation electrician and seems very, very conscientious about following code, getting things right and not cutting corners (he lectured me about the way one of our outlets was wired, explained how to do it more correctly/safely and what kind of outlet to use to not have problems).forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
None of my other tools cause the lights to dim. The only other think that causes this is the garbage disposal (go figure) it causes the low voltage lights under the counter to dim for a second when it is turned on.
A little more about the wiring, keep in mind old house and i bought it this way. From the panel in the main house there is a 220 breaker that runs the garage. So 220 goes from the house panel to a sub panel in the garage. Where it spits to 3 110 lines. (i think this is not ideal)
One runs the lights and the other two are divided up between the two walls. each having its own braker for its outlets. The lights dim when i have the lights (2 8 foot florecents) on in the shop and turn the DC on. No other tools are on.
WT, your original post said "When i turn this thing on the lights in the house go dim for a few seconds." A few seconds is a long time, IMHO. When I fire up either the DC or the table saw (1.5HP Jet), lights dim a tad, but just for a second or maybe 1.5 secs at most.
Seems like it might be a good idea to get a qualified electrician out to take a look at your whole set-up. Besides probably needing the DC on a 20-amp circuit, it wouldn't hurt to just be sure the general arrangement isn't hokey. Not that I have any idea, of course, but that's what I'd do.forestgirl -- you can take the girl out of the forest, but you can't take the forest out of the girl ;-)
Yeah a few seconds, not sure about the actual time. I am in the garage so i cant actually see them dim just going by what the wife says, Hmm so maybe the dont dim at all... I did have the house inspected when we bought it and he said it was all wired fine.
WT, I have a few problems with the info in this thread. You need to find out if the lights in the house dim briefly (flicker) or literally takes several seconds. The former is ok. The comment made about lights dimming being ok does not have enough information. If your incandescent lights dim for the duration the tool is running and they are not on the same circuit but are on the same subpanel, I would have an electrician check that panel and its feed. I tend to overengineer, but I put in my own 100A sub with over a dozen circuits (mostly 20A) just for my shop (about 500sqft). Fwiw, you incandescents are a better visual of any brownouts or sags than other lighting. You will see the difference more clearly. I hesitate to recommend this, but you can check the voltage yourself with any $15 meter (as long as you do so very carefully). If the line voltage drops more than about five percent on another circuit in your garage, you might need that sub rewired. If in doubt, call the guys who are licensed to "follow the code". If you have flourescent lighting dimming more than a brief flicker or even at all, then I would both upgrade to electronic ballasts, and have the sub circuit checked. Think you said these lights are on a separate circuit. Btw, your shop lights should only ever be on a separate circuit. Again overengineering, but my shop lighting is not even on the sub that the tools use. Andy
Hi wisky,
Sounds like you need either a new dedicated circuit or find one that doesn't have any lights on it. Some places let you put lights and plugs together on one circuit but I always hated that practice.
Better have an electrician check it out though if you're uncertain.

I have a 1 1/2hp Delta and when I first started using it I would have issues with it starting up (it would seam to take a bit to get going) then it started poping the breaker (on a 15 amp) moved it to a 20 amp and problem just got worse, eventually it started poping that one and would not even start. Called the place I bought it from (I had been using it for about 2 months at that point) and took it in. Turned out to be some sort of starter circuit in the unit that was bad, they replaced a part and it has been fine for the last year (well a bit longer). Not sure if this could be related or not but I thought I would pass this on.
