Can the EY56 series be interchanged with the current Clipsal 56 series?
Yes the 2 ranges are interchangeable . One thing to keep in mind is that the 2 units have different gaskets. With the Current 56 series gasket the IP66 rating is retained if the screw caps are lost or not installed . Unfortunately if the screw caps are not used in in the EY56 series then the IP66 rating can not be guaranteed .
