Installing Progressive Industries EMS

[Subsailor]

Hello all, I will be installing my hard wired Progressive EMS next week. The instructions have an option to install "before the transfer box" and "after the transfer box" (for protection from both the generator and AC power). I am assuming that the after the transfer box is the right answer...right?

Thanks guys, looks like I am going before. Have a great day! It's chilly here in the Pacific Northwest.

I thought the same thing Subsailor... that I'd put it after the transfer switch to protect the coach from either shore power or generator power issues... I mean the thing even shuts down if the line frequency goes out of tolerance... in North America, at least, that's NEVER going to happen on shore power. Also, I figured the current monitoring feature would be handy to control the load if running on the generator. But the guys here convinced me to do it like they've advised you - before, so as to protect the transfer switch as well.

If you're interested, here are a couple of photos of my installation in my Coachmen Pursuit...

Save yourself some hassle and get a section of high strand appliance cord (#6 wire). It's very pliable and makes the installation much easier. You can get it at Home Depot/Lowes.

Now you tell me!



Seriously, that's a great idea. Working with standard #6 THHN is a major PITA.

cut the power line from the incoming source - before the transfer panel...
I installed one in our first trailer after the campground fried ours and 10 other trailers in less than 2 minutes.

we soldit along with that trailer in July and bought a new trailer which wasnt protected...
so we ordered our PI unit from CW 215$ US.

However this time I followed another campers lead by purchasing 2 male and 2 female twist connetors.

I installed the first female connector on the fresh cut power to the trailer line (the one heading towards the PI surger protector) and one male connector on the incoming end of the PI box.

from the PI surge protection box On the outgoing line i installed the remaining female twist connetor and used the last male connector on the line to the panel.

That way we can remove the protector if we sell and reconnect the power with the loss of only 2 connectors.

and today PI has their items on sale for Cyber Monday

Install it before the transfer switch. Not sure about the instructions you have; instructions with mine cautioned against installing after the transfer switch and said it wouldn't work that way. I took the advice of another post and made the install where it could be removed easily, too. Bought two 50A range cords and two 50A receptacles. Put one receptacle on the end of the shore cord, then put a range cord on the power in side of the EMS. On the power our side, I put the other receptacle, then installed the second range cord to the power in side of the transfer switch. Just plug it all together and you're set, but you can remove it and connect the shore cord directly yo the transfer switch if needed. Also, this arrangement ensures nothing that's hot is exposed to shock you.

Stay Warm Glenn!

This is a project I plan on doing as well - would be really great if you can post before & after Picts!

One Mod to the install you may want to consider is installing twist connectors (I think this is what Ron did in his old Sabre). That way, when you decide to upgrade to a Charleston All you have to do is disconnect at the twist connectors and move the EMS to the new rig.

Just make sure to use #6 wire - that appears to be #10 romex in the photo which is not heavy enough for 50 amp service.

Just to make sure, when you guys are saying "twist connectors", you mean these
right?

No Glenn, not those. They are referring to the cord male and female ends. The ones that twist to lock together.

Nice blue wire nuts though !!

That's a 30 amp unit pictured which is why it's #10 romex

Glenn here's a photo of my install. I just used a cut off piece from the coach cable. If and when I ever change coaches I'll worry about if I keep it or let it go with the coach.
