Electrical Connection
Before making any electrical connections to this
unit, check that the power supply is adequate for
the voltage, amperage, and phase requirements
stated on the rating plate.
A wiring diagram accompanies this manual and is
also attached to the inside of the control box.
MT1828G
U.S. and Canadian installations
The MT1828G requires a 15 Amp, 60HZ, 1
Φ
,
208-240VAC, 4 wire service consisting of L1, L2,
neutral and ground. Wiring from the power source
to these units must be a minimum of #16 AWG
copper stranded wire or larger.
General export and Australian installations
The MT1828G requires a 15 Amp, 50 or 60Hz, 1
Φ
,
220/240 VAC, 3 wire service consisting of L1, neu-
tral and ground. Use 90
_
C wire and size wire ac-
cording to local codes.
MT1828E
U.S. and Canadian installations
The MT1828E is available in either 1
Φ
or 3
Φ
mod-
els. Single phase models require a 60Hz,
208/240VAC, 3 wire service consisting of L1, L2
and ground. Three phase models require a 60Hz,
208/240VAC, 4 wire service consisting of L1, L2,
L3 and ground. Wiring from the power source to
any of these units must be a minimum of #8 AWG
copper stranded wire or larger for 3 phase and #4
AWG for 1 phase.
General export and Australian installations
The MT1828E is available in either 1
Φ
or 3
Φ
mod-
els. Single phase models require a 50 Hz,
220/240VAC, 3 wire service consisting of L1, L2
and ground. Three phase models are available in
either Delta or WYE configurations. Delta models
require 50Hz, 208/240VAC, 4 wire service consist-
ing of L1, L2, L3 and ground. WYE models require
50 Hz, 415/240 VAC, 5 wire service consisting of
L1, L2, L3, neutral and ground. Use a minimum of
8.37 mm
2
copper stranded wire or larger for 3
phase and 21.15 mm
2
for 1 phase.
CAUTION:
Single phase units MUST NOT be connected to
the high phase of a three (3) phase system.
High phase refers to a potential of 240 volts be-
tween one leg and neutral. The remaining two
legs will have a potential of 115 volts between
each phase and neutral. FAILURE TO DO SO
WILL RESULT IN EXTENSIVE DAMAGE TO
ELECTRICAL COMPONENTS AND POSSIBLE
FIRE IN THE CONTROL BOX.
THE BLODGETT OVEN COMPANY CANNOT AS-
SUME RESPONSIBILITY FOR LOSS OR DAMAGE
SUFFERED AS A RESULT OF IMPROPERLY IN-
STALLED UNITS.
WARNING!!
Incorrect wiring will result in extensive
damage to electrical components and
possible fire in the control panel.
