ECN Forum Forums General Topics of the Trade General Discussion Area Solid or stranded GEC

All this talk about GECs made me wonder, does anyone use stranded #6 & #4 for GECs. I always do, but someone (a plumber) asked me recently "is that O.K.?" I never thought about it till then, and have had many inspected. 250-66 doesn't specify solid. I think stranded costs more, but its easier in the muscles.

Although 310-3 stipulates conductors installed in raceways, it seems to be the only place where stranded is required. But there may be "Exceptions" elsewhere in the Code.

I use typically use solid because it does not require as much protection from damage as stranded does.

I usually run stranded as it is much easier to work with, and when exposed, easier to install without kinks.

GEC can be solid or stranded, insulated, bare or covered. 250-62

310-3 exception would apply. Therefore, the GEC can be solid when installed in conduit. I'd like to than Don for pointing this out to me previously.
