Electrical Connections - Baldor TS25 Installation & Operating Manual

Electrical Connections Class 1 wiring methods must be used for field wiring connections to terminals of a class 2
circuit. It is the responsibility of the owner/operator to arrange for these procedures to be
performed by a licensed electrical contractor and ensure conformance to all applicable codes
including local codes peculiar to your municipality/city/county and state. Wire size and insulation
type should be as required by NEC (National Electrical Code) and local codes.
Warning: Never connect this generator to the electrical system of any building unless a licensed
electrician has installed an approved transfer switch. The national electrical code (NEC)
requires that connection of a generator to any electrical circuit normally powered by means of
an electric utility must be connected by means of approved transfer switch equipment to
isolate the electrical circuit from the utility distribution system when the generator is
operating. Failure to isolate the electrical circuits by such means may result in injury or death
to utility power workers due to backfeed of electrical energy onto the utility lines.
Warning: Incorrect installation of this generator set could result in property damage, injury or death.
Connection of the generator to its fuel source must be done by a qualified professional
technician or contractor.
WARNING: Be sure the system is properly grounded before applying power. Do not apply AC power
before you ensure that grounds are connected. Electrical shock can cause serious or fatal
injury. NEC requires that the frame and exposed conductive surfaces (metal parts) be
connected to an approved earth ground. Local codes may also require proper grounding of
generator systems.
Intended Use The intended purpose of this generator set is to provide emergency power when the main utility
power supply is interrupted. Therefore, it is important that all the wiring that connects the
generator set with your house, transfer switch, distribution box, battery charger, etc. be properly
installed.
Protection Single Phase circuit protection is provided within the generator. The power output connections
are rated and sized according to the KW of the generator. Proper lead wire from these points to
the automatic transfer switch (or load switching device) is mandatory. See transfer switch
information for corresponding generator input terminals.
Three phase circuit protection is not provided with the generator. When connecting the
generator output to an electrical load, a UL listed circuit breaker with the appropriate ratings shall
be provided within 25 feet of the Genset. Use only copper wires.
