I just added a 50 amp supply to my trailer
We have a brand new 40 foot long Forest River trailer that only has a thirty amp 120 volt supply.
It has a 15,000 BTU AC unit and a residential refrigerator. Three different times the 30 amp breaker would pop and I couldn't quite figure out why
Then after doing some figuring I found out that if the AC unit came on at the exact same time the refrigerator's compressor came on and at the same time the electric water heater was on. the In-rush current was way over the limit of the 30 amp breaker, (they all could run together if they had come on at different times, but not all at once)
With that said; I Left the 30 amp supply and panel completely alone but added a 100 amp 220 volt panel and new 50 amp cord and plug. I changed the main 100 amp 2 p0le breaker out to a 50 amp one.
Then I disconnected the air conditioning feed cable from the 30 amp panel and rerouted it via a junction box to a new 20 amp single pole breaker in the new panel.
I now have the problem solved and have plenty of capacity for a future washer and dryer if I want.
Total cost for the entire project materials was less than $150 and the panel even came with a 2 pole 30 amp breaker, (think clothes dryer) and two 20 amp single pole breakers.
If they can't get it right at the factory we need to do it ourselves !
