Thor recall iota its-50r transfer switch why drv has not??

Do you really think everyone on the forum is beneath you ?

I very well know that that the 50 amp service on our RV’s is 50 amps per leg.

Since there is the very real possibility that BOTH legs could be carrying the rated 50 amps, that does represent a potential of 100 amps through the transfer switch. Running at max potential also means increased temperature, which increases resistance.

A 50 amp service times 2, flowing 100 amps has to have a reserve or it will fail when operating at rated potential.

No different then a 50 amp breaker tripping at a higher then exact 50 amp load.

So, how is a 50 amp rated transfer switch not able to handle 100 amps - plus reserve ?

Play nice here time to move on

There is the possibility that since DRV has only been under the Thor umbrella for a couple of years that Thor just hasn’t caught up yet.

Compound that with Heartland being the managing corporation of DRV.
Heartland has plenty of their own issues, including plenty of failed transfer switches. Adding DRV & Cruisers just adds to the problem.

Thanks you all for your input.
I just going to repair my unit. wait for NHTSA to call me after 72 hours if I do not hear I call next week and post it here.
Hope no one has to go throw this with their unit.


Thanks again.

I assume you are turning the damages into your ins co?

FYI 1/1/2015 Thor bought DRV.

I would think a call to the manufacturer would solve if the unit is on the recall list.

Turning the damages into your ins co no not for this amount it about $1000 to fix it all.



I did call the manufacturer to solve but not one DRV on the recall list. So I went ahead and will repair everything next week.


thanks

Porthole=Are you another one of them that gets upset if someone corrects your statements?
It is simply a 50 amp transfer switch. Period. It could have 4 input poles and multiple feeds adding up to 200 amps, but it is still a 50 amp switch. The rating is the max per lug not the added values. If you order a 100 amp transfer switch it will be much larger and cost more, and will handle 100 amps per lug.
And temperature does not increase resistance in electricity. Resistance will however increase temperature.
The circuit breakers in use in every day products we use are "inverse time" trip breakers. They can have a 20% current overload for 20 minutes before tripping and still meet the design standards. They will trip instantly on fault currents however. Instant trip circuit breakers are available, but unaffordable for everyday use. Only see them usually in critical use designs.
I have 40 yrs as an electrical engineer to back up my argument. How about you?
I'm done with you unless.

No - but your condescending response to many on here does get the ire of some. I guess it comes from your engineering background.

I am far from an engineer, but I did have the opportunity to respond to the first house fire in my city after Hurricane Sandy. It was pretty easy to spot since there was no power/lights in the area and fire was blowing out of the 2nd floor bedroom windows.

It was also pretty easy to spot that the home owner “electrical engineer” should not have wired his own generator into the panel and left that to a professional (along with his other wiring).

I guess the laws of physics have changed that with an increase in temperature, and electrons moving about faster, that there is not resistance change in copper conductors. Good to know

And - i’ve waited awhile, thinking something would change, but now - I’m done with you and your pompous attitude.

We're all on the same side: aren't we?
