The J501 is torpedo shaped to fit through a 58mm diameter hole in the ceiling. All the cables are securely clamped and they exit from either end of the junction box. This is in contrast to other junction boxes where the cables are generally not clamped and often exit at different angles making it hard to push or pull them through the hole without risking damage or loosening the connections.
Wiring is fast and simple. The J501 fits comfortably in the hand and the cables can be clamped for easier connection. Cabling space is maximised with all the terminals arranged on one side and the upper wall on the lid hinges through 360? for unrestricted access.
For wiring, the three plate terminal style in the box is logical and easy to use and separate terminals for flexible cords and twin and CPC cables help prevent damage to smaller flexible conductors.
During installation all the cables are securely clamped, so there is no strain placed on the terminal connections and no risk of exposed unsheathed conductors. The cable clamps can be reversed to allow either single or double cable entry, which allows up to four flat and one flexible cable to be terminated.
