randynavarro Posted March 13, 2010 Report Share Posted March 13, 2010 I couldn't quite tell if these SEC's were size 1 or 1/0. What do you say?

And then regardless of the size, the SEC's are too small for a 200 amp breaker, yes? What am I missing? I'd have to guess #1. Way too small. Someday, when we meet, remind me to smack you upside the head for sticking that tape measure into a live panel. - Jim Katen, Oregon Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted March 13, 2010 Report Share Posted March 13, 2010 It looks like a sub panel. I see this often, start to write it up, and then remember I'm staring at a sub- panel. You sure the service disconnect is not outside, with a main breaker rated at 125 amps. This would be a common set up for a townhouse in this area. Jim-- it was a dead panel-- Randy flipped the switch outside first. [^] Quote Link to comment Share on other sites More sharing options...
randynavarro Posted March 13, 2010 Author Report Share Posted March 13, 2010 I know, I know. I didn't have anything else for scale; no pencils -nothing. Yes, it's a sub. And like you, Brandon, I have to re-load my thoughts and realize this is ok. Quote Link to comment Share on other sites More sharing options...
Erby Posted March 13, 2010 Report Share Posted March 13, 2010 I had the same thought you did, Jim. But I'm way too far away. - Quote Link to comment Share on other sites More sharing options...

Jack Davenport Posted March 13, 2010 Report Share Posted March 13, 2010 There is no way to determine the size difference between a #1 awg and a #1/0 awg from a picture on the internet! Those 2 conductor sizes are way too close in size to determine in a picture and anyone who does is just guessing! One can not determine the conductor size by using a tape measure either. The various types of conductor insulation prevents this as the insulation is made from different materials of different thicness. I think Brandon may hit the nail on the head. You said the disconnect is outside -What SIZE overcurrent is in the disconnect? This will determine what size conductors can be ran to the interior panel. That 200 ampere breaker in the panel is just a disconnecting means,provided there is overcurrent protection in the exterior switch, it is not neccessary. The panel could have been a main lug only panel. Quote Link to comment Share on other sites More sharing options...
