My outside DB Board/Incomer

This is an installation I've had for many years, due to the location I live in, surge and lightning-prone... I had this installed to cut down on surge damage. The contactor opens during unstable power, protecting the house - haven't lost a single appliance or device since using this,

NOTE: The chocolate block is 60A rated... it's only temporary until I can find something more suited... ARB/ACDC/Voltex didn't have the range the second day of January when I needed something. The inside DB board breaker is only 50A though, so still safe I reckon.
