In our prototype, we have represented washing machine,
TV, refrigerator and microwave in place of 15W bulb, while
the Iron with 100W bulb loads. Each Appliance is operated
through a relay of rated 220VAC and 10A. A 10 minutes
warning is sent to avoid complete supply Cut-OFF.
Our meter response was checked for 12 hours continuously
and reading was tabulated. These results are in accordance with
the meter constant.
