Trojan Boat Forum

Does anyone have a AC schematic for the F series to the range/stove? I replaced my Princess stove-top this weekend with a newer 2247 model. This new model is 240 volts, as my old Princess was 120 volts.

I know I can add the neutral back to the breaker to make it 240 or make another run to the recepticle box under the cabinet... but would like to see the schematic first. An email or fax would work. If you have one, please let me know.

Thanks!

Striper-

Not sure what your asking here... Are you saying you want to install a 220V range in your boat? I've never seen that done and I've never seen anything at the docks other than 110V.

Bringing neutral back to the breaker won't work OR are you saying the range is 220/110 selectable based on the wiring?

I have a wire diagram for the f-32--post your fax # and I will do it tomorrow morning

Jav, sorry for the confusion...I meant 240 volts. I will correct my original post.
Indeed, I can run 240 to the stove. Just wanted to see how Trojan ran their breaker set-up.

I am installing a new stove which requires 240 volts. My old unit was 120 volts.

Thanks.

Perhaps I'll learn something new... I was not aware of anything other than a 110V AC system in our sized boats and the related dock / shore power. Are you planning on running this from a 240V generator or do you have that voltage available as shore power? Also, I've never seen a 240 volt breaker on a smaller boat in the US.

Jav, I'm no electrician, but taking two 120 feeds, (2 shore power inlets delivering 120 each), wired appropriately, through a proper sized breaker and gauge wiring, will deliver the 240 volts I need. I just need the schematic.

Most stove/oven combos as well as onboard clothes driers, for example, can't deliver enough, running on 120.

One of my customers is an electrical engineer and is stopping by tomorrow to explain and show me how to perform this task...hopefully, I will understand and report my findings. In the meantime, a schematic from Trojan is greatly appreciated.

Ah- now I understand what your trying to do... but it may not be as easy as you think. 240 is indeed 2 - 120 legs but they must be "phase shifted" 180 degrees. In other words, you can't just take any 2- 120 legs and make 240.

We in the states call 240 "single phase" which is technically incorrect. Our 240 is actually 2 phases of 120 (alternating opoosite of each other) with no neutral leg. And, the important part is that to get 240 V (measured as RMS - Root Mean Squared), Each 120 leg has to be alternating exactly opposite of the other leg or you'll get something less than 240 Volts.

A schemtaic isn't going to help you unless you know what your input power is IE. a 240 Volt generator, or 240 volt shore power- (2) 120 volt shore power legs will very likely NOT get you 240 volts.... does that make sense?

You will need to have two separate 30 amp 120v feeds into you boat or one 240v feed in order to get 240 volts into your boat. You will have to replace the main 120v breaker with one that can shut off both 30amp 120v feeds or a breaker that can shut off the 240v feed and have a double breaker that can supply 120v on two legs to the stove. You will need to run a new 12-3 with ground wire to the stove as the current wire would force you to lose the neutral wire and the gauge of that wire is probably too small anyway.

It can be done but you won't do it with the OEM electrical panel.

Yes I agree you can't feed it with two 120v 30 amp legs as they are the same phase. You would need a single 240v supply from the shore box. I have not looked that close but most shore power is either 30A -120v or 50A-240v so you would need a cord set of the latter and still the OEM panel would not be sufficient.

Is the stove able to be wired 120v? That sure would be easier.

Thanks, as mentioned, I'll figure out what I need to do and report back.
