Water Heater Insulation Resistance: ISI Standard
Electrical safety standards are crucial for appliances like water heaters. The insulation resistance ensures that the electrical circuit is properly isolated from the metallic body of the appliance, preventing electrical shocks.
The Bureau of Indian Standards (ISI) specifies the minimum required insulation resistance for electrical appliances. For an electrical water heater, the insulation resistance between the appliance's body (chassis) and its connecting cable must meet a certain threshold.
As per relevant ISI standards, this minimum insulation resistance value is1.00 mega \(\Omega\).
- Standard Requirement: Minimum Insulation Resistance
- Measurement Point: Between the body of the electrical water heater and the connecting cable
- Specified Value (ISI): 1.00 mega \(\Omega\)
This ensures a safe level of isolation between the user, the appliance body, and the electrical supply.
