110 power

Yahoo Message Number: 84675
Maybe you guys can help. We are parked in GA for the winter in our sticks and bricks. Have not put in a 50 amp circuit et for our coach. Ran a 110 line to the coach and plugged in using an adapter. We are getting nothing. Shouldn't I be able to get some power to run lights?

Tom,

If your coach is equipped with a Surge Guard or something similar, you may not be getting enough voltage. Or, your transfer switch is stuck to the "generator" side. Start your generator with the shore power disconnected and see what happens. The transfer switch normally defaults to "generator." Start with a voltage check. You also want to consider the condition of your coach batteries. Once the transfer switch goes to "shore" and your inverter becomes a battery charger, depending on your batterie's charge condition, your shore voltage can drop way down. This will be especially true on a 110V extension cord. If this is what you have, you may have to run the generator long enough to charge the batteries, or lower your battery charge settings. (you did check the output directly at the adapter)

Tom,

Before you get into this too deep. Is it possible that extension cord is going into a GFI protected circuit?? That circuit is tripping as soon as you plug the coach in??

I have the extension cord going into the inverter via 30amp then 110v adaptor. I do have to say that it has worked in the past.

Tom,

Do the red lights on your surge guard illuminate when you plug into 110 vac? If so, are they indicating normal input power?

Tom,

I have use 110 by running it through the 50 amp cord using the, 30 amp adapter, and the the 110 adapter. I'm not sure how or where you would plug into the inverter. I do use a 12 gauge extension cord.

I am no electrician but my familiarity with a 50amp plug is that it is actually 2 separate 50amp lines. There is an L1 and an L2 going into the coach from your 50 amp plug. Using an adapter to 30amp and/or 15 amp will only energize 1 of the 2 lines going into the coach. This is probably what is causing it not to work as expected.

Sorry but that is not quite the case. The 30 amp adapter cross connects L1 and L2 of the 50 amp power cord to the single 120 leg of a 30 amp service. Both L1 and L2 are alive at 120 volts. The 20 amp adapter just allows the 30 amp to be plugged into normal household outlet but not one that is GFI protected as most outside outlets are.

Don,

I routinely plug into a 20a GFI outlet with no problem. What is it in the coach electrical scheme that would prevent accepting GFI - the SurgeGuard?

Happy 2012 RIP!

No. I have plugged into gfi outlets with my Surge Guard and no problems.

I use a "cheater" box that allows me to plug into two 15-20 amp outlets, one to power L1 the other to power L2. This effectively doubles my available power, but will not work on a GFI circuit, and the two outlets must be on different circuits or there is no benefit.
