This replacement 6 way, 2 pin cable junction box is ideal for light fittings that require multiple power feeds from the main power cable and saves trying to insert many wires directly into the output terminal of a transformer or LED Driver.
With the terminal blocks only allowing smaller 2 core cable to be installed this junction box takes into account the ability to split the load and reduces the heat directly at the output terminal.
These are very common with under cupboard kitchen lights that require these junction boxes as they are known over time to fail.
