Square D™ Whole Home Plug-on Neutral Electronics Protective Devices

These Square D Whole Home Electronics Protective Devices are compact and affordable surge suppressors designed for installation in QO or Homeline Plug-on Neutral load centers.

How to sell surge protection

Square D offers a Whole Home Surge Protective Device to fit your needs and protect every home you service. Whether you need a device that is installed directly into a QO or Homeline load center, like our Plug-on Neutral options, or a device that will be outside a load center, like our versatile HEPD options, we’ve got you covered. We offer protection that can connect to any brand load center to keep you and your clients covered.
Assessing the situation:
• What type of load center installation does the customer have?
• What option would work best for that situation?
• In remodeling situations, are there finished walls or exposed sides? What's the easiest to install?

Ease of installation
