Electrical Phase Conversion
Electrical phase conversion will require a change from single-phase to three-phase or an opposite conversion change
from three-phase to single-phase. Each of these conversions will be explained separately as follows:
Three-Phase to Single-Phase
1. Disconnect blue and yellow wires from terminal L-3 of the terminal block
2. Connect yellow wire to terminal L-1 of the terminal block. The black wires should remain connected to L-1 of the
terminal block as it was originally manufactured.
3. Connect blue wire to terminal L-2 of the terminal block. The red wires should remain connected to L-2 of the
terminal block as it was originally manufactured.
4. Field wiring for the heater power supply will eventually be connected to terminals L-1 and L-2 of the terminal block
when the product is installed.
Single-Phase to Three-Phase
1. Disconnect yellow wire from terminal L-1 of the terminal block
2. Disconnect blue wire from terminal L-2 of the terminal block
3. Connect blue and yellow wires to L-3 of the terminal block
4. Field wiring for the heater power supply will eventually be connected to terminals L-1, L-2, and L-3 of the terminal
block when the product is installed.

The heaters rating plate will need to be modified because the conversion altered the electrical characteristics of the
heater. This rating plate is placed on every Commercial Electric water heater produced by Bradford White Corporation.
Phase conversion kits above contain rating plate overlays related to the newly created electrical parameters. Follow the
instruction on page 8 For placement of overlays.
