So bascially those whole house surge protectors that they sell at Lowe's and Home Depot aren't worth the money that you would spend on them because they only protect the breaker/fuse box? Because nothing is protected unless the device you are protecting is plugged directly into the protector?  I'm not an electrician, but I would think that it adds another layer of protection.  Am I wrong?

To sum it all up ... No whole house surge protection is necessary, but you should use a PDU between the outlet and your miner, because the PDU will protect the miner directly?  Is that what you are saying?  I still don't completely understand why having both a pdu for your rigs and whole house surge protection isn't the optimal solution.
