* For values of slot width or length not corresponding to those specified, select the largest torque value associated with the conductor size.
Slot width is the nominal design value. Slot length is to be measured at the bottom of the slot.
Note: If a connector has a clamp screw such as a slotted, hexagonal head screw with more than one means of tightening, test the connector
using both applicable torque values.

Battery type. Starting batteries are usually the lead-
acid type and are sized according to the engine
manufacturer's recommendation for a particular
ambient temperature and required cranking time. The

ADC 2100 uses three 15-second crank cycles
separated by 15-second rests for larger models. Refer
to the generator set specification sheet for the required
battery cold-cranking ampere (CCA) rating.
1.8.7
Battery Chargers
An engine-driven, battery-charging alternator charges
the battery whenever the generator set operates.
Engine-driven systems can quickly restore the charge
used in a normal cranking cycle.
When the engine is not operating, a very low charge rate
from an AC-powered battery charger is usually sufficient
to maintain a full charge on the batteries. Select an
automatic float/equalize battery charger with a 3 amp or
greater rating.
Use separate, self-contained battery chargers or units
built into the automatic transfer switch. Run leads from a
transfer switch-mounted battery charger in conduit
separate from the conduit that holds the generator load
cables or remote engine-start circuits.
