Re:Help! I'm scared! Re: 220v hookups 2011/09/17 12:11:24 (permalink)
I do understand what 220 is but I am really ignorant concerning the connections.  We didn't think it was possible that the fair provided a male plug because that obviously allows a chance for someone to be electrocuted.
 
I am planning on having 220 coming into my outside box and splitting it at the breaker box.  Every plug in the trailer has circuit ground.  That allows me to use a generator.  Let me try to rephrase my questions so we can keep the issues separate.
 
After some more checking on a marine website I found an input box (outside the trailer) that has male ends instead of the weather proof outdoor boxes found at lowes which have a female end.  Is that the type of box I will need?  If I use that type of box then I would need a female/female connector to plug the generator in.  Is that correct?  The generator plug is three prongs so that is the type of input box I would plan on using.
 
Regarding using the 110 from a fair.  It sounds that the fair 110 line would run to a 110/220 converter.  This would then plug into my outside input plug which gives me nomal' 220 power at my breaker box.  Since it would now be 220 at the input box this would be business as usual.
 
Thanks for the help and I am sure you will be able to help make me profitable!

Thanks for the links and answers so far.  I do understand what 220 is but I am very ignorant regarding the connectors available.  I am getting closer to understanding the full requirements.  I would like to separate the two issues.  I will have 220 going into the trailer breaker box and then split it at the breaker box.  I do not have anything that requires 220.
 
I plan on using a 50 amp generator.  I will need a 220 three prong male plug in on the outside of the trailer, correct?  This allows me to plug in the generator 220 output.  Is this correct?  I have seen references of 30a to 50a conversion.  OIther than the electrical carrying capacity are the plugs different?  But, it sounds like I will need the 50 to 30 converter.  I assume that would be coming out of the 110 to 220 conveter?
 
Now to using 110 which the fair provides.  My plug in on the outside of the trailer is for 220v.  So it sounds like I will need to use a 110 to 220 converter which would then plug into my 220 input box.  Or would everyone recommend using a transfer box that allows me to plug 110 or 220 into it and let the box do the work?  It seems pretty easy to unplug the generator and then plug in an extension cord, not sure it is worth bothering with. 
 
Thanks

You don't understand as long as you are asking about 110/220 volt converters & transformers.   ... There is no reason to use these.   ....  A 50 amp or 30 amp service box is already 110 volts on the hot legs.
What is the name & model number of your service panel? 
What is the size of the main breaker and is it a double pole breaker?
Your trailer should have a 30 amp MALE plug or a 50 amp MALE plug to connect into a service box which will have a female outlet.  Do you have the MALE plugs?   ...OR, does your trailer just have a connection box which will require 'hard wiring' to a service panel?

The fair should be providing one of these 3 type outlet panel/connections.
 
30 amp  
 
50 amp
 
Or a panel with 20 amp 110 v outlets

At this time the inside of the trailer has a double pole breaker box.  Isn't that the only way that I can use 220 input with 110 devices?  One circuit is pos to neutral and the other circuit is neg to neutral?  Each 110 circuit has a 20 amp breaker.
 
The outside of the trailer has nothing yet.  But, I planned on using the generator 220 output and plugging this into an outside box which allows me to get better use of the total current.  I was planning on a generator plug in something like this on the outside of the trailer
 
 
 
So, if I have a 220 plug on the outside of the trailer wouldn't I need a 110 to 220 converter to plug into it with 110 from a fair?  I realize I could just run an extension cord into the trailer and use it from the inside. 
 
I have the double pole breaker box installed as well as the wiring for lights as well as some electrical plugs. 
 
I can change the input box to be 110 if necessary.  I hope I have finally made myself clear on what my issues/questions are. 
 
Many thanks on helping an ignorant person.  I realize it isn't easy when you are working with someone who knows very little.

  No such thing with AC current.    ... You are talking DC current, of which you don't have.   Each of those single pole breakers only puts out 120 volts.  There is no need for transformers of any kind for 120 volt service.     ... 120 & 240 volt is the standard line voltage. This was changed in the US, from 110 & 220 I think in the 1960's (?).    You get 240 volt service by using TWO 120 volt circuits together (120 + 120=240 volts).  This is the US standard.   European residential standard wiring is 230 - 250 volts based circuits (hot legs).

  A US made common generator puts out 120 volts on two hot legs if the gen set can supply 240 volt service.   There is no need for a transformer.  You only need to match the outlet receptacle with a the correct MALE PLUG.

   1st)  ... you didn't say what size the double pole main breaker was in the main panel.     ... There should be incoming electrical wire to the main panel, are these in place? Or, do you have to install these wires?
swohio
I have the double pole breaker box installed as well as the wiring for lights as well as some electrical plugs.   ...
    I presume you are again referring to the main panel box: or another one?????

swohio  ...  I can change the input box to be 110 if necessary.  I hope I have finally made myself clear on what my issues/questions are. 
   Is this another box outside the trailer???   You stated the outside has nothing.
 
 
OK .. since you stated the main breaker is double pole, it should be a 30 amp or a 50 amp breaker.  If it is a 30 amp, I recommend changing it to a 50 amp.   Pull out the existing breaker and take it to the hardware store and match it with a 50 amp replacement.    You stated there is nothing on the outside, ... so next install incoming wire with 25 ft. of slack with a 50 amp male plug.     Buy about 30 ft of 6/4 outside power cord; connect into the top of the power panel and put a 50 amp male plug on the outside end. 
 
Now, buy or make  a 30 amp male to 50 amp female pig-tail to use with 30 amp service boxes.
 
You should now be set to go.

OH   ... buy and keep a voltage tester on-hand to test the service boxes before connecting to them.   This can save damaging expensive cooking equipment, or starting a fire if the service box is wired wrong. 
 
And, this little one is good to check outlets when there is a problem.

How about hiring an electrician to do the work before you get electrocuted or cause a fire?

You need to get some professional help also, and learn to do a few searches on line on your own. You ask a question and someone tries to help you only to find out you didn't even know enough to ask the correct question. So I wasted my time (45 minutes) on line trying to help you. And the pros on here do their best to help those that try and help themselves, with both Roadfood and online searches. But don't worry what happened yesterday won't happen again. I'll just read your post and laugh.

This is not a DIY forum. The OP obviously has no knowledge of what he is attempting to do.
Electrical is not something to take on if you have no knowledge and are unaware of the dangers.
Do you know the difference between the ways the a/c and d/c wiring is done? The OP does not and could kill someone.
God bless edwmax for having the patience to try and explain how electricity works, but after 30 something posts, the Op still has no clue and needs to hire a pro.
I don't have a problem helping or sharing information, but I do when someone comes here looking for hand holding, has spent no time of their own researching things that are at their fingertips and is easily obtained through google search.
The good Dr said the rest.

Many thanks for the inputs.  I did a lot of searches trying to obtain info.  But, when you have never done something search engines aren't that useful which is why I ended up here and will become a member.  Most things that people do are fairly simple after someone shows you how to do it the first time.

I am now a roadfood insider subscriber.  I will certainly learn more than my $20 fee on this site!
