    Dear Experts,

    I am planning to connect the 50A ammeter to my home 220V AC line in order to monitor the peak current my whole house electrical appliances consuming at specific times.

    I have drafted a circuit diagram (attached), please suggest further.

    thanks,

    It would be much much safer to use one those meters that clamp on the supply cable. No risk of you doing anything wrong and, if you use the right unit, you can download the data from the device to your PC for later anaysis which is what I do.

    The thread will be closed as the forum doesn't talk about lethal voltages.

    My meter box still has one of those old-fashioned kWh energy meters with the rotating disk.

    It's easy enough to monitor the energy consumption at any given time if you have one of those types, a stop-watch and a torch if it's dark. I'm not sure if the modern electronic kWh meters have a display which gives you the information you need in a simpler way.

    Yes dear! i do have that conventional meter at home. I do get readings once or twice a week as it requires me to go downstairs and record the reading every time. I searched for a device that could automatically sense, record data of voltages, amperes, and power usage with outages, while connected to one of my home pc via wifi but the unfortunate thing is the available devices are not here in my city area. it would require me to buy from internet with no Warranty of it.

    If you could suggest me one good idea i would really appreciate that.

    Thanks,

    Reminds me of a little project a friend suggested many years ago. An optical transmit/receive device is "mounted" to look at the rotating disk side-on through the kWh meter glass pane. The shiny disk edge has a dark marker which could possibly be detected as it intercepts the optical beam with each revolution. The opto device interfaces to a battery powered micro-controller. The micro counts & times the disk revolutions and then saves data for later evaluation. I imagine one could interface the uC to a small ISM band radio transmitter allowing one to send the data off to be remotely logged & observed at a nice warm spot in the house. Turn up the electric heater thermostat and watch the change!

    Opening the supply feeder to attach an ammeter is simply too dangerous for a casual interest in electrical usage. A clamp-on meter of the other techniques above are acceptable.

    Otherwise, the thread runs into this part of the ToS -
