. Connect the LSP’s Grid Detect
ion Circuit (GDC) Wires to the Grid Side of
an Automatic Transfer Switch (ATS) or Microgrid Interconnect Device
(MID)
WARNING: HIGH VOLTAGE. ENSURE MAIN BREAKER IS OFF. MAIN SERVICE LINES ARE ALWAYS LIVE.
AVERTISSEMENT: HAUTE TENSION. ASSUREZ-VOUS QUE LE DISJONCTEUR PRINCIPAL EST ÉTEINT. LES
CONDUCTEURS DE SERVICE PRINCIPAUX SONT TOUJOURS SOUS TENSION.
Tools
: Wire stripper and wire splice connectors
NOTE:
The GDC monitors the presence of grid voltage. The GDC must be installed so that it is not
backed up by storage. Land the
“
Grid Neutral
”
wire at the most upstream neutral bar or terminal
possible. Extend the
“
Grid Line
”
wire via suitable wire splice connector and land it on non-backed-up
circuit breaker or perform a supply-
side connection (or “line
-
side tap”) on a wire that will lose power in
a grid outage.
The 12 AWG wires in this circuit must have overcurrent protection per local code.
Connect black wire
to a portion of the
electrical system
that will lose power
in a grid outage
