2.8GENERATOR AC NEUTRAL
CONNECTIONS
Generac uses an UNGROUNDED AC neutral. Grounding is recommended only at the main service entrance. If the neutral wire is grounded and one of the phase loads becomes grounded, the excessive current opens the load circuit breaker or collapses the generator field. The actual result depends on the electrical characteristics of the particular installed generator.

Standby generators installed with automatic ! transfer switches will crank and start
automatically when normal (UTILITY) source voltage is removed or is below an acceptable preset level. To prevent such automatic
Storage batteries give off explosive hydrogen gas. This gas can form an explosive mixture around the battery for several hours after charging. The slightest spark can ignite the gas and cause an explosion. Such an explosion can shatter the battery and cause blindness or other injury. Any area that houses a storage battery must be properly ventilated. Do not allow smoking, open flame, sparks or any spark producing tools or equipment near the battery.
Battery electrolyte fluid is an extremely caustic ! sulfuric acid solution that can cause severe
burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces, etc. Wear protective goggles, protective clothing and gloves when handling a battery. If the fluid is spilled, flush the affected area immediately with clear water.
Do not dispose of the battery in a fire. The battery is capable of exploding.
Do not open or mutilate the battery. Released ! electrolyte can be toxic and harmful to the skin
and eyes.
The battery represents a risk of high short circuit current. When working on the battery, always remove watches, rings or other metal objects, and only use tools that have insulated handles.
2.10.1 VENTED BATTERIES
The electrolyte is a dilute sulfuric acid that is
!harmful to the skin and eyes. It is electrically conductive and corrosive. The following procedures are to be observed:
•Wear full eye protection and protective clothing,
•Where electrolyte contacts the skin, wash it off immediately with water,
•Where electrolyte contacts the eyes, flush thoroughly and immediately with water and seek medical attention, and
•Spilled electrolyte is to be washed down with an
Lead acid batteries present a risk of fire because they generate hydrogen gas. The following procedure are to be followed:
•DO NOT SMOKE when near batteries.
•DO NOT cause flame or spark in battery area.
•Discharge static electricity from body before touching batteries by first touching a grounded metal surface.
Servicing of batteries is to be performed or supervised by personnel knowledgeable of batteries and the required precautions. Keep unauthorized personnel away from batteries.
Recommended batter is Group 26, 12VDC, 550 CCA/75 AH minimum. All batteries must be at 100 percent
