Electrical codes are in place to protect people and machinery from issues that can arise when operating appliances. Among other things, these codes account for electrical surges and provide safety margins, particularly for continuous loads. For appliances that draw current continuously, such as a freeze dryer, the Canadian Electrical Code requires that the branch circuit be sized to carry 125% of the continuous load (i.e., the breaker and wiring must exceed the nominal continuous current). Therefore, an appliance drawing continuous current on a 15-amp circuit should not exceed a continuous load of 12 amps. For an appliance drawing continuous current on a 20-amp circuit, it should not exceed a continuous load of 16 amps. Many freeze dryers manufactured outside of Canada do not meet these electrical requirements as outlined by the CEC. LyphLine is dedicated to servicing appliances and, when necessary, retrofitting them to meet the safety standards required for operating freeze-drying equipment in Canada.
