I'll check when I get back to it one day this week

I do not think he changed any fuses. Like I stated it was originally set up on 220 when I bought it so I really don't think it would have been necessary for a 440 setup. Reverse the scenario's then I agree, those would need to be looked at. Thanks

Little backstory. The mill was (when I purchased it) wired to a 220 with a stinger leg. I moved locations and the power in the new building was 480 with a transformer and the "local there" electrician said, let's just wire everything on 440. What the hell I said as it works it works and I...

Let’s not gloat as many people have successfully rewired an electric motor from 220 to 440 and vice versa, It’s not rocket science and the amazing thing is, the manufacturer even tells us how to do it On the Motor cover of all places. I appreciate your help and feedback though.

Thanks

I’m certainly not an electrician. Basic wiring is not a problem and I can trace out a wiring diagram. Next time I am at my shop I’ll locate T1 & T2 and look for the wires. Thanks

I swapped the 6,5,4 and 1,7- 2,8 - 3,9 together in the past to try to get the motor to run on the 220V and when I jumped the relays in the back of the machine the motor would work but......

I’ve rewired the quill motor but it doesn’t run unless I jump the contact’s in the back of the machine and it will only run in one direction but when the machine is put into low range or high range, the rotation will need to be changed and problem #1, problem #2 is the fact that it’s not safe...

Thanks, I’ll look into this

It's a Bridgeport Series II and there's more to the mill than just the 1HP (could be 2hp come to think about it) motor as there's a large electrical panel on these machines and they are using the 440 wiring in more places than just the motor. Else, that'd be a great idea.

That's a lot more $ and work than a switch

The largest draw I run is the air compressor on the 220, but other the start it's not drawing that large of a load. Possibly 30%. 440 is just a mill and the load doesn't really show on the meter as it's just a 1hp motor. Thing is, only one mill is 440, the other mill/lathe/bandsaw/AC and such...

I have an MEP804B Genset. I have some items at my shop wired for 220v 3PH and some items wired for 440v 3PH. When I need to switch between the outputs I have to open the panel door, remove the 12 nuts on the panel plate and change it's position and rear attach 6 nuts and reassemble the...

Exactly, with no given context it's very confusing and difficult to accurately respond to.

Do you mean the 25amp battery charging system circuit breaker?

This is exactly what I have done and it cranks and fires right up like there's never was a problem. Until the breaker (FU1) and Shunt (MT4) arrive, I am running the genset in this configuration

I took S10(1) and S10(2) off and touched them together and nothing as I suspect S10(2) does not have a good connection somewhere

I ran the generator yesterday and I checked the continuity between post on the MT4(1) & MT4(4) and they show continuity when running and a running voltage of 27V. I don't know if this fuse between the two post is good/bad but

No I store it inside my shop at the door so that the exhaust goes out the bay door and it stay's safe and dry no matter what the weather is like. I could load it into the back of my truck and bring it home as it will fit with the tailgate up in a 6.5' truck bed but I think I can get this now...

Thanks!
