Surge Guard on 28BHBE

Thinking about installing a 50 amp hardwired surge guard on my 28BHBE. Has anyone done this?

Did you get access to where the shore cord enters the trailer or did you add it at the breaker panel?

This may not be a rig specific question. The answer should apply universally.

If I were installing a hardwired protector, it would be in a location close enough to the main breaker that I could terminate it w/o cutting the 50a cord. Just reconnect it to the surge protector and jumper the output back to the breaker.
Another thing to consider is the ability to see the indicator on the surge protector if it has one.

I agree with nort, this is probably a rig specific question. I bought a pole mount for our first TT (30A). When we got the 5th I bought a hardwire (50A). Our panel is located low on a kitchen cabinet next to the stairs. Installation access was via the basement. The "walls" are held in place with easily removed screws and gave good enough access for the install. I also installed the remote indicator close to the panel.
Both units were Progressive Industries and I've had zero issues with both. Progressive seems to be a little more pricy than some of the others but they get good reviews and I think this is one of those things not to go cheap on. They also have incredible customer service, I had a question after install and placed a call on Sun afternoon to the 800 number. A guy called me back in about an hour with an answer (Sunday afternoon!). And like nort also suggests, it was close to the panel so I didn't have to cut the original cord so I can restore it to original if needed.

Welcome to JOF

If your TT has a 30amp system a 50amp surge guard isn't required..., if it in fact does have a 50amp system (added A/C, etc.) then a 50amp surge guard would be the correct choice.

I hardwired my EMS to the outside of my 30amp shore cord box, basically replacing a junction box that was in the same area.

The best/easiest location to add the surge guard is where your Shore-power cable enters the TT. This will put it between the shore power cable and your AC breaker box.

Mine enters at the rear storage compartment, which made installation easy. Click on my SOLAR album below to see a picture of where I wired in my whole house surge protector in the storage compartment (last picture on right). The way I wired it, it works with the shore-power and with my inverter.

I have always used a whole house model in our TT's (and houses) with no problems. As for monitoring voltage levels, I have AC, DC and SOLAR Panel meters inside the TT.

One little hint, I always hook my TT up to the CC 50Amp service outlet when available, as these receptacles are very seldom used and are in much better shape than the abused 30Amp outlets. If you wiggle the cable on some to the 30 Amp outlets the voltage fluctuates, not very good for the TT's electronics, and may cause some power-guards to trip.

This surge protector setup works for me, but may not be an option for others.
