Often confused with
| Confused with | How to tell them apart |
|---|---|
| Standard Romex / NM two-screw clamp connector | SE cable saddle clamps typically feature a wider, oval-shaped mouth opening and a contoured saddle specifically dimensioned to hold flat/oval SEU or multi-conductor SER cables without pinching or damaging the jacket. |
| Service entrance wedge clamp | Wedge clamps are drop-wire tension clamps for overhead aerial service drops, whereas saddle clamps are conduit box fittings with screws. |
