caryseidner Posted November 21, 2008 Report Share Posted November 21, 2008 I found this device connected to the main disconnect in the main panel. There was some writing on the top of the it, but I couldn't read it with my mirror and flashlight. Anybody know what it is/what it's for?

Mark P Posted November 22, 2008 Report Share Posted November 22, 2008 Originally posted by inspector57 Surge protector for the entire house, but it looks like they have double tapped offf the main. That's a no-no. That is how they are always installed. I may get corrected, but I believe that is how they are designed to be installed.

MTL_Inspet_Man Posted November 23, 2008 Report Share Posted November 23, 2008 Installation of surgeptrotector appears to be proper only issue I have is it is hidden behingd that 2x4 making swapping it out if the need ever occurs a job for a contortionist Quote Link to comment Share on other sites More sharing options...

Read the manufacturers installation instructions. Read the instructions from the manufacturer of the main breaker. Quote Link to comment Share on other sites More sharing options...
Bill Kibbel Posted November 23, 2008 Report Share Posted November 23, 2008 I think we do this every year. See the last post: www.inspectorsjournal.com/forum/topic.asp?TOPIC_ID=5310 Quote Link to comment Share on other sites More sharing options...

hausdok Posted November 24, 2008 Report Share Posted November 24, 2008 Jeez, Bill just pointed you to this graphic showing how they're supposed to be installed. What more could you want? OT - OF!!! M. Quote Link to comment Share on other sites More sharing options...
caryseidner Posted November 24, 2008 Author Report Share Posted November 24, 2008 I just blew up that diagram, and it looks like it is showing the surge suppressor is double tapped into the first breaker. Yes? Quote Link to comment Share on other sites More sharing options...

I was more concerned with how the suppressor works and what the manufacturer has to say about it. Quote Link to comment Share on other sites More sharing options...
homnspector Posted November 24, 2008 Report Share Posted November 24, 2008 Cary, you are correct, that's what it shows and that is not the way it should be installed. What more could you want? Maybe a correct diagram. Quote Link to comment Share on other sites More sharing options...

What more could you want? Maybe a correct diagram. I was doing some googling on them last night, and I couldn't say for sure because I didn't have a manufacturer or model or much of anything, but it looked like these suckers are supposed to be installed at the first breaker in the panel. I guess that is going to protect the rest of the circuits. Seems to me like if that is how they are supposed to be installed - in the first breaker - then it would be difficult for anyone other than a good sparky to do it because everything would have to be shifted around.

homnspector Posted November 24, 2008 Report Share Posted November 24, 2008 Cary, These things have 3 wires. 2 are connected to the (2) 110 volt bus bars by way of 15a breakers dedicated to that purpose (not double tapped unless it is a brand that allows 2 wires). The third wire is grounded. If there is excess current on either bus (like 600 volts) it is diverted to the ground. The only reason for connecting them to a breaker (rather than directly to the bus) is so the supressor doesn't start a fire if it shorts out. I don't beleive it matters where in the main panel it is installed. Most that I see are double tapped either under the bus terminals or another breaker which is not the correct way. Big deal? Probably not but I would call it out. Quote Link to comment Share on other sites More sharing options...

You're also correct that it doesn't matter where on the bus you connect the supressor. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
