We are supposed to leave for Jackson MS Friday morning.  Does anyone have any experience with the 7300 Series Electronic Converter/Charger, 45 Amp?  The guy that has been comverting my electrical in my trailer (added AC, 3 120 volt receptacles, 5 12 v lights) is having a problem blowing breakers.   He had never dealt with this type of converter charger before but it is also his frst time working on my living quarters.

I know everything worked before because I had powered through the original little starter breaker box that came with the trailer.  This guy said I needed this converter charger, so I bought one.  He said I know longer needed the little breaker box, so he took it out.

He started the electrical a month ago, he has only worked on it for 2 1/2 days, procrastinated the rest of the time.  I would call him and he has one excuse after another as to why he had not been working on it.  I kept asking if it was to much, should I take it somewhere.  No No this is a piece of cake he would say.  Blah Blah Blah...A whole nother story...

SO...I am freaking out now, because we leave in the morning.  Kicking myself...because I should have followed my gut.

Any experience out there with one of these???  What could be causing them to blow my breakers?

Hard to say without seeing the installation.  I looked at the mfg. web page and there are good trouble shooting tips. Faulty ground wireing, etc.....

I assume he has "read" the instructions. Hope it works out.

Circuit breakers can trip because you are drawing too many amps thru it ...or they are weak and failing and need to be replaced

Or your electrician could have UNDERwired your new circuits...i.e. too small a gauge wire for amps drawn

Sounds like you need a second opinion...
