Leakage current
13.2
60335-1(ed.3)
Standard: IEC 60335-1:1991, 3rd Ed.
Sub clause: 13.2
Sheet No. DSH-482
Subject: Leakage current
Key words: - leakage current of appliances with a 3-phase heating element and a 1-phase motor.
Decision taken at the 40th CTL meeting 2003
Question:
How is measurement of leakage current for appliances with a 3-phase heating element and a
1-phase motor made?
Rationale:
See question.
Decision:
When using figure 6 or figure 7, only the switches in the phases other than the phase for the
motor are disconnected, if the construction of the appliance permits so. Otherwise all 3
switches are disconnected in turn, the motor being separately supplied. Then the leakage
currents are measured separately and the values for the motor and the relevant phase for the
heating element are added.
