Ovens designed for 240 volts (check your oven nameplate for power
requirement) will operate satisfactorily on a minimum of 208 volts, but
with a 25% reduction in heater power. If your power characteristics are
lower, contact Despatch industries.

Models LBB1-69, LBB2-12, -18 and -27 must be hardwired to the electric supply using 10 AWG or
larger wire suitable for at least 75 °C (167 °F).
