Junction box solves solar cable problem
Spelsberg's new PV48 junction box provides a specific and inexpensive solution to the annoying problem on photovoltaic panels, of standard cables being too short. Designed to seal cable diameters of between 4-7mm, the PV48 allows simple cable extension, providing a quick, secure cage clamp connection within a discrete IP65-rated junction box.
Chris Lloyd, Sales and Marketing Manager for Spelsberg, comments: "As standard, photovoltaic panels rarely have more than a maximum of 2m of cable attached. This means that installers regularly need to use a junction box or install expensive extension cables to extend the cabling length. The PV48 is the first junction box on the market designed for this specific job, as such it fulfils all the requirements for the application."
The PV48 junction box has two in-line cable entry points that use M16 cable glands to ensure quick and secure cable entry. The connection is made using a cage clamp terminal: a 5.5mm flat blade screwdriver is used to open the connection point, which the exposed wire is pushed through. When the screwdriver is removed, a secure connection is made automatically. The box cover clips into place, forming an IP65 seal.
