electrical box questions

[DLB2990]

I have seen on here that some electrical boxes do not have motor contactors. I have to replace an old Federal Pacific and was wondering what everyones opinions are on what to replace it with and where to get the parts needed to clean up the box.

Here is what I use

There will be some wiring changes you will need to make when changing out that Federal Pacific contactor.

If you need any help post back here.

I have been using a relay from Grainger to replace the motor contactors in the electrical box. It is still considered the "motor contactor" in the box...even though it may not look like one you use. I will try to get an updated picture of one in a box that is in use. I have some pictures of one that I have been trying to build...but I have not gotten much further with it due to issues I have with changing the current wiring diagrams and schematics of the pinsetter. Not sure if I want to change the current design or leave it as is.

Not sure if I want to change the current design or leave it as is.

How about the "easy to find and repair" design? It's like the "Keep It Simple, Steve."

On second thought, I don't know if Brunswick did it this way, or am I out of my mind. Since the pinsetter runs in sequences, how about the electrical box? There could be a diagram for each of the functions of the electrical box. Such as diagramming where the high voltages come in and are distributed; and another diagram for the safety switches, one for the cross conveyor system, etc. I think that this would make things easier for troubleshooting.

On third thought, I am out of my mind.

I am right there with you.

Hey Steve! Is this the part number: 1EHX2 Relay and 1FC15 Relay Base for the motor contactor? Did you get the wiring schematic for this and the motor start relay: 1EHW4 Relay/1EZ95 Relay and 1FC14 Relay Base? I just need help with the wiring and appreciate all the help from you and Lonnie!! Thanks, Bruce

This is the contactor I use. I Was able to simplify the HV terminal strip. I also have din rails on the bottom of all my electrical boxes. Mt TDM relay, MSR, and Motor Contactor all mount on the rail as I install them.

Anyone have an overload or breaker wired into that?

It shouldn't be too difficult to wire in a breaker or overload if the motor doesn't have one built in.

The overload would be wired in series with the motor's "hot" lead. (Black is hot; white is return; green is chassis (earth) ground.)

Yes...those are the part numbers. I have some diagrams but they are not in a form that would do you much good at this point. I am working on putting something together. Something you could do is wire the contactor by following the same instructions for the Deltrol installation...but just jumper the left two sets of contacts together along with doing the same for the right hand contacts. Jumper the top and bottom using 14 guage wires. It should resemble the Japanese wiring diagram. If you have any issues...give me a call.

I realize that Tom
Was just wondering how it worked with that grainger contactor bud

Mike, I would suspect that it would work with the Granger contactor as it would with anything else of that type of set-up. The trick to it is finding a suitable location for mounting the breaker. A cheap and dirty way of doing it would be to hang an in-line fuse holder (available at RadioShack) and use a 15 amp glass fuse. Of course, anytime the motor hiccuped, the fuse would blow.

I have some mini breakers I was going to mount on the electrical box next to the 1 amp fuse. I think 2 of my 24 motors have overloads and I have no overloads in the electrical boxes. Yeah, something bad is gonna happen before I get to put them in. Thanks for starting this thread and jinxing me.

The overload situation is the real problem, I doubt that with Federal Pacific contactors that his motor protection is in the electrical box. Thus he will have to add an overload for motor protection. The overload is the costly part.

I use these in my equipment now because they are three phase, but you can see what you need.
