• Make sure entire muffler-side of generator is exposed
(Figure 7).
Figure 7 — Temporary Cold Weather Shelter
Wind
• Ensure a minimum of two feet clearance between open
side of box and nearest object.
• Face exposed end away from wind and elements.
• Enclosure should hold enough heat created by the
generator to prevent problems.
CAUTION!
NEVER run unit indoors; Do Not
enclose generator any more than shown. Remove
shelter when temperatures are above 40°F [4°C].
RECEPTACLES
120 Volt, 20 Amp GFCI Receptacle
This receptacle (Figure 8) is protected against overload by a
20 Amp, push-to-reset, circuit breaker.
Figure 8 — 120 Volt AC, 20 Amp GFCI Receptacle
Generac Portable Products MC4000 Generator
Use each receptacle to operate 120 Volt AC, single-phase,
60 Hz electrical loads requiring up to 2,400 watts (2.4 kW)
at 20 Amps of current. Use cord sets that are rated for
125 Volts at 20 Amps (or greater).
120/240 Volt AC, 20 Amp Locking
Receptacle
Use a NEMA L14-20 plug with this receptacle. Connect a
4-wire cord set rated for 250 Volts at 20 Amps (or greater)
(Figure 9). You can use the same 4-wire cord if you plan to
run a 120 Volt load.
Figure 9 — 120/240 Volt AC, 20 Amp Receptacle
This receptacle powers 120/240 Volt AC, 60 Hz, single
phase loads requiring up to 2,400 watts of power at
20 Amps for 120 Volts; 4,000 watts of power (4.0 kW) at
16.7 Amps for 240 Volts. The outlet is protected by a
20 Amp push-to-reset circuit breaker.
CAUTION!
Although the 120/240 Volt outlet
states it has a 240 Volt 20 Amp rating (up to
4,800 watts), the generator is only rated for
4,000 watts. Powering loads that exceed the
wattage/amperage capacity of the generator can
damage it or cause serious injuries. Loads of
240 Volts powered through this outlet should not
exceed 16.7 Amps of current; 120 Volt loads should
not exceed 20 Amps.
