LD7 RCBO

Old metal LG4 and LG6 units have a breaker that is now obsolete.
The new RCBO that is used in our lifeguard units to replace the FG breakers has a bigger face that doesn't fit into the hole cut into the metal, which is why a bigger hole is required to fit the new breaker.

Dimensions for the LD7 breaker are shown in the pictures below.
