If it doesn't say on the generator it can be configured for a higher voltage, then an electric motor shop may be able to reconfigure the generator windings and voltage regulator for your desired 480, the fuses and wiring may also need upgrading to 480 volt compatible. Too much hastle to hack into it

Sand filter pump, model SF20110. How can I rewire?


rewire ?? are you meaning to say you'd like to operate it on a different voltage than its set for now ? not all motors are changeable , if one is a (multivoltage) type motor it will have a name plate to say for example 110-240 or 208-277 does yours say anthign like this on it ??

LP126HD3A rated for 265 volts AC single phase I have 240V ac single phase, how can I use this unit on 240V ac


You'd need to supply a "Buck-Boost" transformer to do this properly. Technically, the 265 VAC is one hot leg and neutral of a 480 VAC 3 Phase Y system that measures 277 VAC. The 265 number comes from this:

265 is the standard nameplate voltage for a 277 volt motor or AC unit.

230 is standard name plate for 240.
200 is standard name plate for 208
460 is standard name plate for 480.
110 is standard name plate for 120.

Most electricians call the hot leg / neutral circuit "277V AC".

Some popular "Buck-Boost" transformers will convert 208 to 240 and 240 to 208 volt systems, and 240 to 277 and 277 to 240 volt systems - among many other variations. These are auto-transformers as the primary secondary windings share a connection. KVA ratings differ significantly from name plate because of this fact. You should contact a qualified electrician to not only size, but wire the transformer for you. Failure to install a Buck-Boost transformer - and running this unit on 240V AC mains will cause premature failure of motors - fans and compressor due to overheating. This can also result in a fire hazard.

I hope this helps and good luck!

How do i rewire an air compressor from 110 volt to 240 volt


This can only be done if the motor is switchable between 240 vac and120 vac If it only says 120 vac on the motor you have a problem.

How do I know if my Hotpoint oven 920 years old0 is on a 220 0r 120 line? The serial plate says 120/220.


An oven uses both 120 & 220 -- actually it would be 120 volts and 240 volts or nominally, 110 volt and 220 volt.

The 120 is used for the lights. The 240 is used for the heating elements.

A 240 volt breaker (nominally 220 volt) -- supplies both 120 and 240 volts depending on how the supply is connected to the appliance.

There will be a 240 volt (nominally 220 volt) breaker in the main panel for the oven. This is two 120 volt breakers side-by-side with their toggle switches connected together with a strap across the top of the toggles.

I am working with a Dayton 2YU39. The name plates states that it has to be powered by 208 volt system. There's a 3-phase panel and a single-phase panel. The 3-pahse panel L1 to ground is 118 volts. L2 is a...


Hi,
Here's what I think but you will have to check it out...
The fan motor in the 39 heater is a 120V fan there fore it cannot be hooked to the 240 which potentially could have the high (wild) leg as one of the fan legs...
The 240V 36 unit probably has a 240v fan motor....
Now if you were to make sure that the leg that fed the motor was a 120V to ground leg then you will be okay...
Hope you understand where I was going with this...

Need to rewire from 480 to 240 need coolant pump diagram for colchester # 348337 3 phase motor


Assuming that the motor has 9 leads and the wire numbers are still on the wires, for 240 volt 3 phase connections:

Connect T1, T6, and T7 together with L1 (A phase)

Connect T2, T4, and T8 together with L2 (B phase)

Connect T3, T5, and T9 together with L3 (C phase)

If you're not sure which of the incoming wires from the supply are L1, L2, and L3, just pick one. If the rotation is wrong just swap any 2 (TWO) phase wires.

We have a Vulcan Roast Oven VO008 and it is wired for 480 volt 3ph, can it be rewired to be 240 volt single phase?


It could be but, the expense of replacing all the 3 phase controls would cost more than what it would be worth. Sell it and use the proceeds to purchase a single phase unit or if you are wanting to use it in a commercial building, see if you can have 3 phase installed by your electric provider.

Muh -07-4 480 volt heater


no, you need to rewire the motor.
the heater elements may not let you do that, since it is rated for 480v.
