Thomas & Betts BC-4 – Frequently Asked Questions

1) What is a Type C conduit body like the Thomas & Betts BC-4 used for?
A Type C body is an inline pull and splice point. It sits between two runs of conduit on the same straight axis and gives you an opening to pull conductors through or make a splice without cutting in a box. The BC-4 is die cast aluminum and built for EMT systems. If you need to turn a corner instead of running straight through, a C body is the wrong shape for the job.
2) Will the BC-4 conduit body connect to EMT, or do I need a rigid fitting?
The BC-4 is made for electrical metallic tubing. It's listed as an EMT conduit body, so it mates into EMT runs directly. For threaded rigid or IMC you would want a threaded conduit body instead. Crouse-Hinds also builds a combination EMT Type C body, the C15MTC-6 in the Condulet Series 5 line, if you need another option for the same inline application.
3) How much wire fill does the BC-4 conduit body give me for splices?
32 cubic inches of interior volume. That is what you work from when you run your box fill calculation for the conductors and splices landing inside it, and it's generous enough to make up several connections rather than just pull through.
4) Which cover and gasket part numbers go with the Thomas & Betts BC-4?
Two cover choices: CV-4 die cast aluminum, or SCV-4 stamped aluminum. Gaskets are GKV-4 in composition or GKN-4 in neoprene. Pick the neoprene gasket where you need a tighter seal against moisture; the composition gasket is the general-purpose option. Cover screws on the BC-4 are retained stainless steel, so they stay with the cover when you open it up for maintenance.
5) What is the Crouse-Hinds equivalent to the Thomas & Betts BC-4 conduit body?
The closest cross-brand counterpart is the Crouse-Hinds C15MTC-6 Condulet, which is also a Type C conduit outlet body built for combination EMT connection. The Thomas & Betts BC-4 is likewise a Type C conduit body, so both serve the same purpose - a straight-through pull and splice point in an EMT run with a removable cover for access. The BC-4 is die cast aluminum with a 32 cubic inch wiring chamber, so confirm the C15MTC-6 trade size and volume match the run you are tying into before swapping one for the other.
6) How much clearance do I need to mount a BC-4 conduit body?
Lay it out from the published case dimensions: A is 7-1/4 inches, B is 7-7/8 inches, C and D are both 2-1/2 inches, E is 4-3/16 inches, F is 3-17/32 inches and G is 1-3/8 inches. That body is large enough that it needs real room off the wall and along the run, so check it against tight ceiling spaces or behind-equipment locations before you commit the layout.
7) Is the BC-4 conduit body ordered individually or in multiples?
Thomas & Betts sells the BC-4 each, but the order multiple is 2, so quantities go up in pairs. Inner packs hold 2 and the outer carton holds 10. If you are buying for a large job, work your count in twos to avoid a short line.
8) Is die cast aluminum the right material for the BC-4 in a damp or industrial space?
Die cast aluminum resists corrosion and holds up in industrial and commercial environments, which is why the BC-4 is specified for plant conduit networks as well as commercial and institutional buildings. In wash-down or wet locations, pair it with the GKN-4 neoprene gasket rather than the composition GKV-4. Aluminum is not the choice for direct contact with wet concrete or highly caustic chemical exposure.
9) I need to change direction in an EMT run - is a Type C body like the BC-4 the right part?
No. The Thomas & Betts BC-4 and the Crouse-Hinds C15MTC-6 Condulet are both Type C bodies, which are straight-line pull and splice fittings with the opening on the side of the run, not angle fittings. For a turn you want an LB, LL, LR or T style body in the matching trade size. Use the BC-4 where you need access in a continuous run, such as a splice or junction point in an EMT extension.
10) If I standardize on one brand of Type C body across a facility, what should I check between the BC-4 and the Crouse-Hinds C15MTC-6?
Check three things. First, trade size - both are EMT Type C bodies, but the fitting has to match the tubing already run. Second, wiring volume, since the BC-4 offers a 32 cubic inch chamber and your conductor fill calculation is tied to that number. Third, the cover and gasket family, because the BC-4 uses CV-4 or SCV-4 covers while the C15MTC-6 is part of the Crouse-Hinds Condulet Series 5. Picking one family keeps a single set of covers and gaskets on the maintenance shelf.
11) How heavy is a BC-4 conduit body for overhead support planning?
1.73 pounds each. That is body weight only, so add your cover and gasket on top of it. At that weight an unsupported inline body hanging in a long overhead EMT run should be strapped close on both sides rather than carried by the tubing alone.
