F1 Mini Junction Boxes FAQ
Product questions
Find answers about fit, wiring and product differences.
F1 Mini Junction Boxes
01Are all F1 boxes straight-through splice boxes?
No. F1-2T has two entries, while F1-3T and F1-4T provide three- and four-way layouts. Choose the body for the cable route.
02Does a compact box fit any small cable?
The cable must still fit the entry seal, and the conductors must fit the terminals. Check both ranges and the room needed to bend the conductors.
