2.7 GROUNDING THE GENERATOR

2.5EMERGENCY CIRCUIT ISOLATION

METHOD

This prevents overloading the generator by keeping electrical loads below the wattage/amperage capacity of the generator. If the generator is powering only crit- ical loads, within the wattage/amperage capacity, dur- ing utility power outages, consider using the emer- gency circuit isolation method.

Critical electrical loads are grouped together and wired into a separate “Emergency Distribution Panel.” Load circuits powered by that panel are with- in the wattage/amperage capacity of the generator set. When this method is used, it is difficult to overload the generator. The transfer switch must meet the fol- lowing requirements:

•It must have an ampere rating equal to the total amperage rating of the emergency distribution panel circuit.

•Have it installed between the building’s main dis- tribution panel and the emergency distribution panel.

2.6TOTAL CIRCUIT ISOLATION

METHOD

When a generator capable of powering all electrical loads in the circuit is to be installed, use the “Total Circuit Isolation Method.” It is possible for the gener- ator to be overloaded when this isolation method is employed. The following apply to the transfer switch in this type of system.

•Ampere rating of the transfer switch must equal the ampere rating of the normal incoming utility service.

•The transfer switch is installed between the utility service entrance and the building distribution panel.

The National Electrical Code requires the frame and external electrically conductive parts of this equip- ment to be properly connected to an approved earth ground and/or grounding rods. For that purpose, a GROUND LUG (Figure 2.2) is provided on the gener- ator mounting base. Consult a qualified electrician for grounding requirements in the area. Grounding procedures must meet local regulations.

DANGER

Do not connect the ground wire to any pipe that carries a flammable or explosive substance

– FIRE or an EXPLOSION may result.

Proper grounding helps protect personnel against electrical shock in the event of a ground fault condi- tion in the generator or in connected electrical devices. In addition, grounding helps dissipate static electricity that often builds up in ungrounded devices.

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.

2.9TRANSFER SWITCH SIGNAL CONNECTIONS

‹2.9.1 PRE-PACKAGED ATS

If the generator is to be installed with a pre-packaged transfer switch, it is necessary to connect the control wires to the generator and set position two of the four-position dip switch to OFF.
