I recently had the 15a circuit breaker behind the Zamp Charge Controller blow, the result was no charge to my two batteries. This got me thinking about surge protection when plugged into our home 120v or at RV parks. I have two questions:

1. Any ideas why that CB blew? I use one roof top 100w panel and one 100w portable?

2. Any new ideas concerning surge protectors?

I've read the 2012 tread on this subject. I have a fully loaded Hawk, compressor refer, everything is working great otherwise, no problems since fuse replaced.

Thanks,
Brian

I purchased a 30amp surge protector at Camping Work for $100+, good insurance.  I need to pick up one that I can use at home.  I have a 30amp - 25' cord and plug it into the surge protector and then into shore power.  When you use shore power at a campground, make sure the power (circuit breaker) is off before you plug in. Once you everything plugged in, turn it on.  jd

I'm of the opinion that the fuse for the Zamp had nothing to do with a surge.   As I recall, there is no AC going to the controller.   I suspect that your panel(s) might have put out more than the 15 amp fuse could handle, but I am not certain of that.

 

A surge protector is a good idea when hooking up to shore power.   Like JD says, it's good insurance.   As the shore power connection that comes with the camper is only a 15 amp, I don't see a need for a heavy duty power cord, but rather just a good, heavy gauge extension cord.   I'd have a doggone (30 ampere to 15 ampere adapter) to hook into the surge protector and/or the campground power.

Thanks all for the suggestions, I did install a surge protector in my garage and bought a 30a one for RV parks. I'm going to try adopting a procedure when plugging in my 100w panel, I'll turn it away from the sun when plugging it in to the rear plug, might prevent a little surge! It has only happen once.
