8.2.1 Utility Power
Utility power is a reliable and ideal source of energy for the MSA
electrofusion processor, however, it is not practical to access such
a source in most field applications. When fusing with utility power,
a dedicated connection to the service panel is recommended, since
the potential amperage draw is very high.
8.2.2 Generators
Fuel powered generators are typically a good source of electrical
power for the MSA electrofusion processor. Minimum fitting power
requirements must be noted, and additional power capacity is
recommended for intangibles (powering other accessories, wear &
tear, etc.).
Prior to beginning a fusion, it is important to insure the following:
• Make sure the generator has enough fuel to complete the
entire fusion cycle.
• Turn off the “auto” or “economy” idle control.
• Recommend a generator with a minimum 30 Amp breaker for
couplings 10” and larger.
8.2.3 Inverters
Inverters are an acceptable AC power source for the MSA
electrofusion processor, though some produce output waveforms
that are troublesome with specific fittings. Georg Fischer/Central
Plastics recommends performing compatibility tests using the
lightest and heaviest anticipated loads before approving an
inverter system. Feel free to contact GF/Central Plastics to discuss
issues regarding the use of inverters.
8.3 EXTENSION CORDS AND PIGTAILS
Due to the high amperage draw of electrofusion fittings, the
use of an extension cord is not encouraged. In the event such
usage is necessary, the following lengths and wire gauges are
recommended:
