Electo switch problem

[irwinsailor]

I hope someone here can point me in the right direction. I am hooking up my new inverter and am having a problem with the 3 way shore power/generator/inverter switch. I have no idea how it should be wired and it is not working. I can not find a diagram for this switch and I am hoping one of you electrical people will know where to look. The switch is a Electro switch corp. T40 Cat. NO. KW40 230388. Thank you.

Gunner, I don't know if this will help or not.\

Hmmm, obviously not. try this
http://www.bluesea.com/ and select Technical and Application Briefs . There are some AC circuits there.

Gunner,
Go look at the instructions for this switch

They look to operate similarly and....DON'T SWITCH THE GREEN!!!!!

Pat’s Blue Seas reference shows how Rotary Selector Switches work*
You could use a Buzzer or Ohmmeter to ‘ring out’ your specific terminal connections in each knob position.

* When they work - they’re prone to failure, especially if switched under load I prefer interlocked breakers..

Well I got smart and emailed electro switch corp with the information. They very promptly sent me a diagram. Now I still have no idea how this thing needs to be wired. The switch works for shore power and generator but I can't figure out where the inverter wires should be if they are not correct from before. I also gave out the wrong number before, it should have been cat no KW40 2303b8 A capital B looks alot like a 8.

From a system point of view the method for wiring your switch depends upon the following:
Do you have an inverter/charger and, if so, what is the ac current rating of the internal transfer switch?
Do you have a remote monitor for the inverter which allows you to defeat "auto transfer" as well as "auto charge"? This has a bearing on how you might use the internal transfer switch if it is rated to carry the entire vessel current.
Do you want the inverter to "serve" your entire ac breaker panel or do you have a "split bus" whereas the inverter output is dedicated to inverter-only load breakers?

Depending upon the above info you may only use your manual transfer switch to switch between gen and shore, making it easier to wire and more automatic.

Gunner, if you look at the documents on the url I posted below you will find wiring diagrams to help you wire up your system.

There are options to have your invertor handle only certain parts of your A/C panel or all of it.
