Rolling Blackouts - Potential Equipment Damage
With possible planned rolling outages this Winter, considerations need to be made to protect expensive equipment such as Heat Pumps, Boilers, TV and Audio equipment, EVs etc etc from damaging surges when power is restored.
I am considering a timed contactor for the whole house to delay being restored to Grid to allow the surges to settle.
I've seen the damage power restoration can do. It is very much like the knock you hear in the pipes when leaving the garden tap switched on with a hosepipe connected and quickly opening and closing a tap.
The inrush surges generated may defeat or damsge SPDs, therefore, I am looking to delay reconnection to protect delicate equipment.
Something to consider, an SPD may not be enough.
