Does unplugging an electrical device when not in use achieve

Does unplugging an electrical device when not in use achieve some goal (i.e. saves electricity / money or prevents electrical surges from shorting out the appliance or device) -- or is unplugging electrical devices when not in use based on the "unplugger's" lack of electrical knowledge of what is truly going on? We have a cleaning individual who routinely unplugs all electrical appliances in the kitchen when not in use. If this is achieving some useful goal, I will not direct them to stop doing it. If, however, there is no benefit to unplugging electrical appliances (or other devices) when not in use, then I will direct her to leave all our connections plugged in as it is somewhat of a bother to use an appliance you thought was plugged in and operational, only to discover that someone else had unplugged it without telling you, as if it were common knowledge such things not in operation should be unplugged.

I am a contractor who had 2 crews working in the sub floor

I am a contractor who had 2 crews working in the sub floor crawl space replacing duct work (below floor horizontal HVAC unit) and installing a tankless water heater (requiring GFCI outlet to operate heater). After the installations (both crews working same time), the homeowner noticed their microwave oven clock was flashing as if the electricity went out and then came back on. No big deal they reset the clock and the microwave appears to operate normally. Now the big problem, the all electric Jen air range / stove / oven is having issues. there appears to be no power to the digital control display panel, but the range top burners (all 4) work perfectly but without each power indicator light coming on. So no oven, oven light, temperature setting, etc. appears to be working. No other electrical appliance in the home has been affected is this a problem with the circuit board and are my crews at fault or was there a power surge from the utility company? I need clues and help.JA: Can you guesstimate how old your Jenn-Air is? And just to clarify, what's the exact model?Customer: I am not at the homeowners location but they have said it is 5 years old and has had previous control board issues?JA: Do you plan on doing the work yourself?Customer: Oh No! I just need some information on why this happened and if I need to pay for repairing it.JA: Anything else we should know to help you best?Customer: One last bit of information that might have bearing. During my initial inspection of the crawl space I noticed that the really old original Knob & Tube wiring is still in use and might be powering appliances as well as outlets and lights.

Hello. We just had a windy storm pass through and our power went out for a brief moment. Unfortunately, my halogen track lighting systems went out as well as the stairway light (all on the same circuit).JA: I'll do all I can to help. How long have you been dealing with this?Customer: Just started to dig into the problem. The CFL light on the stairway was flickering on and off. The wall switch is a dimming switch. I took it out and replaced with a regular wall switch. The hallway light now comes on but my two track lights don't.JA: Do you plan on doing the work yourself?Customer: YesJA: Anything else we should know to help you best?Customer: That's it.

My treadmill in the basement was plugged in and I usually

My treadmill in the basement was plugged in and I usually leave the power turned on. For some reason, though no one was using it, the belt started moving on its own. Usually you have to select a program and press the start button. No one was there at the time it started. I unplugged it and saw the upper socket where it was plugged in was fried and the treadmill plug prongs looked like they were a bit charred. I plugged the treadmill into the bottom socket and it worked. The plastic in the top socket was a bit melted. The breaker was not tripped and no other problems were noted in the house. I will have an electrician in on Monday to replace the socket, but wonder if there is any danger?

I have a 1500 watt heater whose ground prong / third prong broke off - could I use something else to keep it safe like use an adapter or always make sure to plug it in GFCI outlet (which has the same effect as a ground prong, right?)
