30 AMP OPS - Leroy Eckert - 08-13-2006 10:39 Pete: I'm with you on the body parts completing a curcuit. Don't care for that. But, maybe I can figure my deal out. It would be helpful if BB gave a better description of what to expect. Leroy Eckert 1990 WB 40 Niceville, FL ----- Original Message ----- From: "Pete Masterson" To: Sent: Sunday, August 13, 2006 3:22 PM Subject: Re: [WanderlodgeForum] Re: 30 AMP OPS Bill, This is great information --- and makes good sense to me. I really appreciate it as it didn't make sense to me that two 30 amp breakers would trip with 16 amps load on each... or 30 and 1, etc. I'll have to poke around at the cook top to see what voltage it operates with (I assumed that it was 220 as it's a 2-burner version of a 4 burner cook top I had prior to converting my home to a gas range). I suppose, however, that it could be 110v as it only has half (or less) the demand of the 4 burner home version. Hopefully I can find the papers on the cook top in the blue box as the manufacturer's plate (if it is present) is inaccessible without disassembling stuff. I have a strong respect for electrical devices and so far I have successfully avoided completing any circuits with any parts of my body involved --- and I plan to keep it that way!

No, that will provide 30 amps total for both legs, any way you wish to distribute it over the 2 legs. 0-30, 30-0, 15-15, etc. > Like I said I have never > really studied 110 and phases and such.

I assume you already have the other required connection: a 30A female to plug into the coach aux connection and the 30 male plug that is at its other end. Usually, BB has wrapped the female end in yellow tape to differentiate it. > It really doesn't > make sense for leg one to go away if the aux power > leg two is sensed but it appears that is the way it > is wired. Well, to many it does, as it permits 60 amps to be provided when the 50A (really 100A) is not available. With this methodology, each leg has up to 30 amps for a total of up to 60A. Otherwise, 30 is shared between both legs, as explained above. Nevertheless, that is the way most BB automatically-switched-systems work. > Thanks for the help.

Everything works in my coach, have had very few problems other than light bulbs etc. I didn't want to start plugging in cables and create stray voltage and cremate one or more of a gazillion relays in the bus. I'm sure that could happen and cause me all kinds of %$#@. Strange things can happen. Short story. Four years ago I purchased a 56" HD wide screen TV. Didn't need it but thought I did. Living in an area where electrical storms are common, you live there also, I plugged it into a constant voltage transformer and a surge suppression device. Two months ago we had one of those storms. It cremated the transformer, the surge suppresion device and the TV. Fortunately, I purchased an extended warranty. The $69.00 pool TV on 24/7 and doubles as a night light outside made it through. Go figure. I guess what I'm saying is, my beautiful coach is without warranty and I am very careful. As always, the forum has come through again with its knowledge and experience. Very educational. Hopefully it will help others. This forum is like Fox news. You report, we decide. Thanks again.

We'll be staying at Morro Bay (Bay Pines RV Park) the night before (with only 30 Amps available). So this discussion of "cheater cords" etc. is quite beneficial.

The 240,000 volt line crossing our property once fell through the 240V house feed, scorching driveway concrete and attic 2x8's, taking out virtually every house appliance, but the coach was protected by a $400 surge protector and was unharmed. Best $400 of insurance I ever purchased. Power company just laughed when I filed a damage claim with them.

It also comes with ONE 30 amp cord and when that one is plugged in at the same time as the 50A with adapter, a relay lifts one leg from the 50 amp cord and connects it to the 30 amp cord. Thus giving you a 30+30 setup rather than a 30. Rich D.

Is is waterproof? Where did you purchase it? Thanks for the help Leroy Eckert 1990 WB-40 Niceville, FL ----- Original Message ----- From: John Suter To: WanderlodgeForum@yahoogroups.com Sent: Monday, August 14, 2006 6:16 AM Subject: Re: [WanderlodgeForum] 30 AMP OPS Morning Leroy, Nowhere (in your posts) have I heard about your having a 50 amp surge protector (I recommend external) which can be the greatest protection for electronics in your coach as it won't be only the relays which will be cremated if you take a surge. The 240,000 volt line crossing our property once fell through the 240V house feed, scorching driveway concrete and attic 2x8's, taking out virtually every house appliance, but the coach was protected by a $400 surge protector and was unharmed. Best $400 of insurance I ever purchased. Power company just laughed when I filed a damage claim with them.
