Hi,
I started rewiring my Delta 50-760 dust collector for 220V operation. I followed the instruction in the switch box to realize that it doesn’t quite match the eletrical wiring.
Has anyone done this 220V conversion on their 50-760 collector ?
I could use your help.
Thx

In what way does it not match?

In the switch box, the diagram shows 4 terminals : (3)----(2) and below them (1)--(~)--(4) in the high voltage configuration.
There are 4 wires in the box labeled (3), (2), (1) and (4). The 220V switch I bought has 4 terminals, but I'm not sure that these terminal are corresponding to the box diagram's terminal. When switch is on, terminal (3) make contact to (1) below it, and (2) to (4) below it. The diagram show (1) contacts (4) as in (1)--(~)--(4). I'll attach a drawing and picture.

Okay,
On the power cord the two hot lines go into the switch, one to each of the lower terminals (i.e., the "off" side) and 1 and 4 out to the motor, each from one of the upper terminals (i.e., the "on" side). 2 and 3 are spliced together and ground is ground of course. The switch makes/breaks the connections between the upper and lower terminals.

I attach the picture
Are you up and running?

Not quite. I just got a wiring diagram from Delta. It confirmed my suspicion of the diagram in the switch box missing crucial information to do correct wiring.
I should be up and running shortly..

If you have any trouble let me know and I will e-mail you my phone number. I could walk you through that in 5 minutes.

Will do !!
Q
Thanks for posting the diagram. I've been following the discussion and planned to do this myself. With the diagram it should be a snap.

Dennis, Quang & Don,
Yep, me too. This would really make my day. Thanks guys.

Did you got yours running ?
Just got mine running today after a trip to home depot for the 6-20 Nema plug.

Q,
My conversion will have to wait a bit but I did capture the pic of the diagram and should be a no brainer when I do. It was 13*F in the woodshop yesterday, heater is on the fritz. It's just too dang cold up there to spend time there.
I will be doing it as soon as it warms up and/or get the heater fixed, which should be today. I'll post my results as soon as I get it done.

I haven't done this specific dust collector. But I can tell you what you need to do to convert the motor to operate on 240 VAC when it was originally wired for 120 VAC operation. As I have done this conversion on other motors in my shop many times.
There are three items that need to be addressed to convert the motor to 240 VAC operations: 1) you need to reconfigure the wiring of the leads in the motor junction box (the information should be on the motor nameplate), 2) you need to change the plug to a 240 VAC plug you will need a NEMA 6-5P (15 Amp, NEMA 6-6P (20 Amp)(providing you are plugging the dust collector into a 240 receptacle, 3) you will need to replace the switch with a double-pole-single-throw (DPST) switch.
I checked the Delta Machinery website and they offer 2 switches for this model dust collector. One switch is around $5 and the other switch is $35. From what I could see without Delta being more specific in the parts list, the cheaper switch is for 120 VAC operation (as you received the machine) and the more expensive switch is for 240 operation (as you would like to make the machine run on).
The main difference between 120 VAC operation and 240 operation is the following: 120 VAC operation uses one hot wire (black) 120 VAC and a neutral wire (white). Neutral is basically ground without getting into extensive AC electrical theory. When using a 240 VAC motor, there are two 120 VAC wires providing power to the motor. And, both wires need to be disconnected when turning off the motor for safety reasons. If you continued to use the switch you currently have, you would still have 120 VAC on the coil when turning off the switch which is dangerous and illegal by the NEC (National Electric Code). Besides, your life is worth more than a $35 switch.
You can either buy a replacement switch and a 240 VAC plug at an electrical suppply store (maybe Home Depot has them), or order the replacement switch from Delta. I can say this, the 240 VAC switch (DPDT) is a lot more expensive at delta than a suppl;y house or Home Depot. I have bought "motor starters from Grizzly for a little more than you would pay for a switch as a replacement part at Delta. I like starters better because if you lose power while the dust collector is running, it will not restart when the power comes back on like it will with a regular switch.
Most importantly, if you do not rewire the wires in the motor junction box YOU WILL BURN OUT THE MOTOR running it on 240 VAC.
If the manual does not specifically show you how to rewire the motor and switch, and you are not completely comfortable doing these changes, HIRE AN ELECTRICIAN. 120 VAC can kill, 240 VAC can kill faster. And even if 240 VAC does not kill you, it will knock the crap out of you.
Electricity needs to be respected!!! As soon as you lose that respect, it will bite you. I have ended up on the floor more than once in my life. Thank God, that was in my teens and 20's.

Rewiring Delta Dust Collector
I saw the comments on here from last year about rewiring a Delta dust collector. I just bought one and just wanted to make sure that there was not a need for a neutral wire. Thanks.
