Installing surge protection at a main breaker panel? A Type 1 SPD can also be installed in compatible Type 2 load-side locations. Type 1 gives you more installation flexibility because it can be used at the service entrance or on the load side of the service disconnect.
UNDERSTANDING SPD TYPES

Type 1 vs. Type 2 Surge Protectors

If you were told to install a Type 2 surge protector at your main breaker panel, you can also use a properly applied Type 1 SPD in that location. The difference is primarily where each SPD type is permitted to be installed.

Important: A Type 1 SPD can be installed at the service entrance or in compatible load-side locations where a Type 2 SPD would normally be installed. A Type 2 SPD is intended for load-side installation and is not used on the line side of the service disconnect.
TYPE 1

Most Installation Flexibility

Type 1 SPDs can be installed at the electrical service entrance or on the load side of the service disconnect.

  • Service entrance applications
  • Main breaker panels
  • Compatible subpanel applications
  • Can be used in Type 2 installation locations
TYPE 1 CAN ALSO SERVE TYPE 2 LOCATIONS
TYPE 2

Load-Side Installation

Type 2 SPDs are installed on the load side of the service disconnect, such as at a main breaker panel or compatible downstream panel.

  • Main breaker panels
  • Distribution panels
  • Compatible subpanels
  • Not intended for line-side service-entrance installation
TYPE 3

Point-of-Use Protection

Type 3 SPDs provide an additional layer of protection close to the equipment being protected.

  • Plug-in surge protectors
  • Receptacle or equipment-level protection
  • Used downstream from the electrical service
  • Complements whole-building surge protection
Shopping for a whole-house SPD? Do not rule out a Bad Wolf product simply because it is labeled Type 1. A Type 1 SPD can also be installed in compatible Type 2 locations when installed according to its listing, instructions, and applicable electrical codes.

Back to AC Section
Shopping for a Type 2 surge protector for your main breaker panel? Most Bad Wolf whole-house models below are Type 1 SPDs. A Type 1 SPD can also be installed in compatible Type 2 load-side locations, giving you the flexibility to use it at a main panel while retaining its Type 1 service-entrance capability.
PANEL MOUNT

Panel-mount models use a built-in 1/2-inch NPT male connection for direct mounting to a compatible electrical panel or enclosure.

LIQUID-TIGHT

Liquid-tight models use a 1/2-inch liquid-tight connector for installations where the SPD is mounted separately from the electrical panel.

RIGID CONDUIT

The HSD240V and PHSD240V are designed to accept 1/2-inch rigid plastic conduit inserted into the enclosure connection. These connections are not threaded and do not use a liquid-tight fitting.

Need Help Choosing?

Not Sure Which Surge Protector You Need?

If you are not sure which Bad Wolf surge protector matches your electrical system, contact us with the system voltage, AC or DC type, application, installation location, and connection or mounting requirements. We can help you identify the Bad Wolf products that best match your application.

Helpful information to send: System voltage, AC or DC, single-phase or three-phase, wye or delta if applicable, equipment being protected, installation location, and preferred connection or mounting style.
For whole-house surge protection: Let us know whether the SPD will be installed at the service entrance, main breaker panel, or a subpanel, along with your preferred panel-mount, liquid-tight, or conduit installation.
For contractors, dealers, and OEMs: Ask about product selection, volume orders, dealer programs, OEM applications, and specialty surge-protection requirements.
