randynavarro Posted February 4, 2014 Report Share Posted February 4, 2014 A client sent me a pic of this service and cable on the outside of her house. Electrician is saying the exposed SEC under the meter is ok as long as it's secured. No protection required. I've scanned 2011 NEC and having a hard time disseminating if protection from damage is required. Any help?

In my area, that cable would not require protection. However, it should be secured, as the electrician said. I don't see that it's secured.

MMustola Posted February 4, 2014 Report Share Posted February 4, 2014 In my area the SEC is always exposed when the service is over head. There should be a clamp every 30 inches. Quote Link to comment Share on other sites More sharing options...
Jim Baird Posted February 4, 2014 Report Share Posted February 4, 2014 That's an overhead service, with sloppy work. The cable is supposed follow structure closely and be fastened at 18". Quote Link to comment Share on other sites More sharing options...
John Kogel Posted February 5, 2014 Report Share Posted February 5, 2014 That cable is protected only by the breaker back at the transformer on a pole somewhere down the street. I don't know how many amps can flow through those SEC's before that beaker trips, but it is a lot. We sometimes see a flexible cable feed from the weatherhead to the meter box, well clamped of course. But below that, it is routed inside the wall, always, and typically in rigid conduit. That is indeed sloppy work and it shows a blatant disregard for the safety of the home owner's family. Quote Link to comment Share on other sites More sharing options...

However, in Philadelphia where houses abut a sidewalk they require conduit over SEC up to 6 feet above grade. Quote Link to comment Share on other sites More sharing options...
