My understanding is that, if there's a cubic inch stamped on the LB, it can be used as a junction box. That's per NEC. Sounds like you have a petty inspector. Around here, the inspector only looks at the work, the permit is pulled for. If the conduit body is stamped with a number of cubic inches, then you can apply the junction box fill rules instead. In any size of conduit that's reasonable for your wires, there aren't nearly enough cubic inches in the conduit bodies!Rule 12-3000 Outlet Boxes & 12-3004 Terminal Fittings The Code does not permit "conduit fittings" to be used as a junction box. Well, for one thing, a junction box cannot use the conduit as support. An LB is not a type of J-box, anyway. It is a fitting. Threaded raceways are permitted to support boxes under certain circumstances.
I'm looking at a 1/2" PVC LB. It's marked 4.5 cu.in. With no splices I pull 3 #14"s in it and thats 6 cu.in. But we are allowed to use it as per the the second sentence of 314 (C) (1). So even no splice exceeds the fill of the conduit body.
Minimum Size of Conduit Bodies Used as Pull and Junction Boxes. NEC 314.28 establishes certain minimum dimensions for pull and junction boxes and conduit bodies to ensure adherence to wire fill requirements and protection for electrical conductors during pulling.
I haven't seen an LB with a tapped hole for a ground screw lately. Is it because an LB is considered a raceway and not a junction box? If it's not a junction box, then making holes in the sides might actually not be the intended purpose.

Regarding specific cases, I see 1/2" lbs frequently used as junctions for the monitoring of butterfly valve switches. There is no way these have the cubic inch capacity required for the 2 to 4 wires coming from the monitoring module or panel, the 9 or 10 wires coming from the 2 switch contacts, plus the wire nuts and maybe an end of line resistor. Just installed an "electric eye" control for my landscape lighting. Ran PVC conduit up the outside wall, installed a LB fitting, a female adapter. Screwed the electric eye into the female adapter and use the LB as a junction box. Is this a code legitimate method?
