How Does an Electric Sub Meter Work?
An electric sub-meter is wired in series with the electrical circuit of the area it is intended to monitor. It measures the flow of electrical current and the voltage of the supply. By multiplying these two values, the power being consumed is calculated. This power consumption is then integrated over time to determine the total energy used, which is typically displayed in kilowatt-hours (kWh).
Legal Aspects of Using a Sub-Meter
The installation and use of electric submeters in India are generally legal, but important considerations must be made to ensure compliance with regulations.
- Is it legal for landlords to install submeters? Yes, it is legal for landlords to install submeters to measure their tenants’ electricity consumption. This is a common and accepted practice for ensuring fair billing.
- How to get a submeter approved? In most cases, submeters do not require separate approval from the electricity distribution company as they are installed after the main meter. However, the wiring must comply with the Indian Electricity Rules and be done by a licensed electrician to ensure safety and prevent legal issues.
- Tenants’ rights regarding submeters. Tenants have the right to an accurate and unaltered submeter. The landlord cannot charge a rate per unit of electricity higher than the rate charged by the local electricity board. The meter reading should be transparent, and tenants should be able to verify the readings themselves.
