120/208v clarification

 
 
Reply Sat 16 Mar, 2013 03:03 am
Hello, I have a commercial BBQ rotisserie that I want to connect at home. The MFG plate say 23amps 4.8kw, 120/208v single phase. Does this mean that I can connect it to 120V or 208 volts? I know that I don't have 208v at home. I was just wondering about the voltage connection.

Thanks,
Steve

Yes and no Steve. It's rare that an appliance can be used on either voltage without a switching of connections within the device. If it isn't explained in the instructions then consult a friend who knows about that kind of stuff

@dalehileman,
Unfortunately there are no instructions on this unit. I cannot find a manual online. Maybe a connection schematic might be located inside the unit. I was just wondering if it was possible that it would run on 120 instead of 208

Thanks,
Steve

@65tbirdsteve,
Dale is probably right. What kind of plug does it have? If it's compatable with your wall outfit, it is probably set up for your location.

@roger,
Thanks Rog for your support, probably

Well 65 I can only suggest you plug it into a 115-v outlet; if it just barely works, then, it's probably set for 208 v

However with the reduced voltage don't leave it on very long because there is s chance of damage at a lower potential

@dalehileman,
Thanks guys. The plug is 208v. It came out of a super market about 10 years ago and was probably used 3 times. I want to make use of it instead of getting rid of it. I was hoping that there might be a 120v option. I'm going to open it up today to see if there is a schematic for hookup. Thanks guys for answering my post.

Steve

@65tbirdsteve,
Well 65 if it turns out only 208 v, you can easily acquire a stepup transformer, even one with the appropriate outlet built-in but be sure it's of appropriate current rating

Dale, please desist from giving this kind of advice as it is obviously out of your league.

Do you have an idea of the cost and weight of a 5 KVA step-up transformer?

Other than that the manufacturer's plate stipulates 120/208 V, so it has to have the adapted connection.

Let's hope 65sbirdsteve will post here what he found upon opening it..

My goodness Tim, I apologize most profusely to all

Not the slightest but I'll look it up herewith

I believe, 65, what Tim is saying here, is that if the plate stipulates both, then the mfr must have provided an internal means, probably easy to those so qualified, by which to switch; but unlikely that the appliance will work on either value without so doing. Doubtless access will require a screwdriver, this facility normally behind removable plate. It's possible also that the corresponding socket is so hidden

A transformer apparently about $100

…but I'd suppose you could find a used one 'way cheaper

@65tbirdsteve,
Why not spend $20 and have an electrician take a look at it for you?

That $20 will be well spent when compared to the cost of having to replace your electrical system, the appliance and/or your house.

Why would you do anything less?
