Do I need a whole-house surge protector or is a power strip enough?

Across specialist electrician communities like r/AskElectricians and r/electrical, the consensus is that a panel-mounted (Type 2) whole-house device such as the Eaton CHSPT2ULTRA or Siemens Boltshield handles large transient surges at the service entrance, while plug-in strips add a secondary, point-of-use layer for sensitive electronics. Many electricians recommend both: a whole-house unit plus quality strips at your computer and home-theater gear.
