INSTALLATION
EG4xxx Owner’s Manual
2.2
Materials required for installation
• Per phase: Use of proper smallest available breakers or rated fuse taps for
the install per local NEC rules. Usually 15A circuit breaker or single multi-
pole breaker depending on phases used.
• Black, red, and white stranded AWG 12 wire; length depending on instal-
lation location. Thermal resistance to at least 75
◦
C. Blue wire is needed in
addition for 3-phase installations. Use wire that has insulation rating greater
than the max voltage inside the panel.
Note: wire colors may vary based on
country and electrical service.
• Electrical tape
• Conduit and couplings as needed
• Mounting and wire organization hardware as needed
• If installed outside, appropriately rated enclosure (e.g. IPX4/NEMA4)
2.3
Tools required for installation
• #0 slotted screw driver (needed if length of CT-wires needs to be adjusted)
• Circuit-breaker finder (if using HomePlug power-line communication)
• Voltage meter
Additionally, for device commissioning and installation verification:
• Clamp-on AC current meter
• Laptop with Ethernet cable

Nomenclature and Symbols
In the US, residences typically receive power through split-phase power distribu-
tion which is provided through two hot legs, a neutral, and a protective ground.
Most commercial and industrial buildings receive power through 3-phase power
distribution provided through 3 hot phases, a neutral and protective ground.
