Help Please - Need Wiring diagram for 2hp 110/220 motor with drum switch

[sck01]

I am trying to replace an old boat lift motor setup and have no clue on the wiring. I was thinking that I could just hook it up the way the old motor and switch are but in researching how to do it, it appears that wires vary between motors and different switches work different. Once I am at the boat lift, I will not have cell or internet so I will not be able to look for an answer if it doesn't match what I have now.

I am attaching the data sheets (Switch and Motor.jpg) for the motor and the switch. I am planning on setting up on the 110 line that is already in place. the second attachment (diagram.jpg) is my rough diagram of the wiring. I would greatly appreciate it if someone could connect the lines to the correct posts in switch and post an attachment with the completed drawing.

looks like only the one uploaded here is the data sheets

Can the conductor out to the boat lift be re-wired to 220V plus ground? @ 110V the current draw will be nasty, the line drop will be severe, and the lifting power developed by the motor will suffer.

Seems like you need an electrician...

I agree with CR.
BTW, I don't think that your motor type is listed on the switch instructions.
It is not a DC motor.
It is not a repulsion Induction Motor. Not many left. I last worked on one over 40 years ago. They were normally reversed by shifting the brush positions.
It is not a split phase motor.
It is not a three phase motor.
It is not a two phase motor. They were phased out in Canada about 80 years ago.
Wait. Ontario Hydro changed over from 25 Hz to 60 Hz about 80 years ago. Two phase motors were long gone already.
There may be some minute exceptions. There are persistent rumors that a two phase system is up and running somewhere.
In what time warp did you find that switch?

I can't stands those &$#*^ drum reversal switches. Nasty pieces of work. Always designed to accept 50% of the wires needed. They can take 30 minutes to get the covers on. Blech.

Two things to remember Keith.
1. The terminals 1,2,3 4 switch the starting winding and are wired diagonally. Power 1-4, winding 2-3.
2. 5-6 switch everything, both run winding and start winding. Think of them as a single pole switch on the wall switching the motor power on and off.
I can't help with the covers.

waross, the switch is new attaching the data tag off the cover.

crshears, the run from the box to the switch is only about 20' there is 12-2 wire already run and an unused 220 breaker in the box. assuming I could just change which breaker the 12-2 wire is hooked to and have 220.

Not to open the box but "what is the advantage of 220 vs 110?" Cost is not an issue as I have all the parts and it is not going to run enough to effect the electric bill. the only thing I have seen is faster start ups. it is not going to affect power / torque output of the motor, correct?

still looking for a correct wiring diagram.

The switch may be new but the connection diagram is over 50 years out of date.
120 Volts versus 240 Volts.
1. A #12 AWG wire is overloaded with a 20 Amp motor.
2. Starting current of about 120 Amps may cause a voltage drop in the feeder to the panel as well as in the #12 wire.
3. Using 240 Volts will cut the Amperage in half. This will cut the voltage drop in Volts in half. This will now be referenced to twice the voltage, 240 Volts rather than 120 Volts. The percentage voltage drop will be 25% of the original percentage.
4. Lower voltage due to greater voltage drop will reduce the motor starting torque.

Wiring the switch:
Call the incoming lines L1 and L2.
Call the switch terminals S1 through S6
Call the motor terminals T1 through T

1. Wire the motor for 230 Volts.
Make the following changes and connection.
2. Connect L1 to S5
3. Connect S6 to T5
4. Connect T6 to S1
5 Connect S3 to T2 & T3
6. Connect T8 to S4
7. Connect S2 to T1
8. Connect L2 to T1
A quick reversal is not recommended.

thanks Bill! that is what I needed.

so regardless of 110 or 220 I need to go to 10ga wire? going to do 220 but running the wire may be "FUN"

 

[waross]

The existing wire will be fine for 240 Volts. The current drops to 10 Amps.
You are welcome to review my connections Keith.
