4. Wiring the Panel
Size all conductors with reference to the overcurrent protection device, ampacity, and voltage drop requirements in accordance with all
local electrical codes. Use conductors rated to minimum of 75°C.
● Connect supply-side Line 1 and Line 2 conductors to the main breaker terminals.
● Connect supply Neutral and Ground conductors to their respective terminal blocks.
● Refer to the table below for suitable conductor gauges and torque requirements.
● Span sub-feed lugs are rated to 200A max.
WARNING: Risk of electric shock. Check that all circuits are de-energized before wiring including generation equipment
such as solar inverters and storage batteries.
CAUTION: The Span Panel is only intended for use on 120/240 V split-phase electrical service.
● Connect Line conductors for all circuits to the respective breaker.
● Connect Neutral and Ground conductors to their respective wire terminals.
● Once all conductors are connected and secured, check that there are no exposed conductors or stray wires. Clean up
conductor routing to ensure no wires will be pinched when re-assembling the autotransformer cabinet and deadfront
assembly.
NOTE: Keep track of circuit labelling. This information will be required during commissioning.
