Surge Guard 41300 Surge Guard 30A Transfer Switch

Shore input is locked out when generator input is powered,Size is easy to mount, but leaves less room inside box for excess wireInstructions provide exact measurement for length of wire leads( how much rubber jacket to remove ), for all 3 cablesShore, generator and output to rv,I installed this to switch between inverter and portable generator for my rv,So the rv shore cord is wired to the generator input and the inverter is wired to shore input,This way I can use campground power if available, generator if notAnd inverter if either source fails,Great addition to my rv at a great price

Original in my RV was blown-out by too much power!Looked exactly like original, fit like original and works like it too. Saved a lot of money by doing it my self. Do not attempt to replace if un-sure. I’m a retired tradesman and my neighbor came over to kibitz and it went well. Pretty much plug and play, just hook it up like the original was.

Perfect, easy to install. One tip, you will need to purchase at least 3 NM connectors. Slight hum, so ensure it is installed in an external compartment.

Using to switch between shore and inverter slight hum which u quickly get use to large delay between power switching with audible clunking that aside unit is performing as needed.

This is not suited for shor / inverter but is OK for generater/ shor power

So simple to wire and works perfectly. I really like that it has a time delay between switching the circuits.

Works as intended. Added in a series with another one to have three inputs for my rear AC. Shore power (main), shore power (secondary), generator power.

Install in my old motorhome and works great

Fonctionne bien

This is working great but it takes a little too long to switch over. All and all a solid item.

This was used to replace the exact same product that had been damaged on our rv. Worked perfectly.Delivery was very fast.

My kingfisher boat, excellent information and well worth buying product
