Installation 
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, 1Φ,
General export and Australian installations
The MT1828G requires a 15 Amp, 50 or 60Hz, 1Φ, 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 1Φ or 3Φ 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 1Φ or 3Φ 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
8.37mm2 copper stranded wire or larger for 3 phase and 21.15 mm2 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.
