The following sizes of services are recommended for all normal applications. It is not
intended to preclude the use of larger sizes where justified by special conditions of load,
voltage drop or voltage flicker.
These service sizes are based on the ampacities of the various conductors direct buried
and/or in conduit (PVC direct buried). Consider cable direct buried if no part of the cable run
is in conduit longer than 20 feet.
For conduit sizes refer to U27.
Size residential services for 80% of the electrical breaker panel as per NEC.
Example: 200-AMP panel x 80% = 160 AMPS. Therefore, a 0AL (stock number 185150) should be used
for the service.
