Last night I heard a loud popping noise in the where I had

Hi Pearl. Last night I heard a loud popping noise in the hall where I had an extension cord plugged in. There is a small fridge and a small oil heater plugged in. I live above a pub which is about 70 years old. The wiring in my room is not stable so I don't use this socket. I'm wondering if it is my appliances causing the problem or if it is a structural problem?JA: How old is the system in question? And have you consulted an electrician yet?Customer: The system is around 70 years old. The landlord is slow with anything to do with spending money. So no electrons yet. The power point made a loud pop and had a slight burnt smell. But it did not trip out my powerboats with safety switch but the power breaker straight away.JA: Do you plan on doing the work yourself?Customer: No I cannot. I have a pacemaker. Also the owner of the pub/hotel is responsible for the fixtures of the building.JA: Anything else we should know to help you best?Customer: I would just like to know what the likely cause might be. Is it my appliances or the building/wiring itself? The landlord likes to blame the tenants for anything that goes wrong with the buildings. This has been ongoing issue for some time and only on one side of the building.

Having trouble replacing a bad motion sensing light switch

Having trouble replacing a bad motion sensing light switch in my home laundry room with a normal toggle switch. Light would not come on so after replacing several bulbs decided to replace the old (Seldon Used Motion sensing switch) I verified the bulb is good by testing in a working lamp. Coming into the light switch box are 3 sets of 3 wires. GROUND: The 3 bare ground wires are wraped together with a wire nut on the end. WHITE: The 3 white wires are tied together with a wire nut. BLACK: Confusing wiring. 2 of the black wires are tied together with a wire nut together with a 3rd short ~4" Back wire extension.(I think so that it is easier to connect it up to the switch? SO 2 wires basically become one wire. The 3rd Black wire coming into the switch box is by itself and looks like it is ready to attach to the switch. (Unfortunately I did not take any pics when I removed the old 3 wire motion sensing light.When I connect the 2 black wires to the single black wire the light does not come on. Also when connecting them to the switch it does not come on. I tested the toggle switch on and off with the continuity tester mode on my meter and the switch is good.VOLTAGES MEASURED:1) 3 Bundled Bare Ground wires to 3 Bundles White Wires = 15V2) 3 Bundled Bare Ground to 2 Bundle Black Wires = 120V3) 3 Bundled Bare Ground to single black wire = 15V4) 2 Black Wires to 3 Bundled White Wires = 65V5) 2 Black Wires to 1 Black wire = 65 V6) 3 Bundle White Wires to single black wire = 0VNOTE. The Electrical outletts in the laundry room(2) also do not seem to be working right. I measure 65V across the 2 slots that should be 120. But I do measure 125V between the Ground pin hole at the bottom and the Right Side slot It seems that they did work last time we tried to use them for the iron.Q1: is there a fix I can make in the switch box that will fix the light and the outlets so they all have 120V accross them?Q2: Should I be concerned that between the ground and one of the wires is 120V. Or will that get fixed when I fix the light switch box.Q3: DO I need an electrician to fix this or can you talk me thru or describe what I need to do to fix this?

I have a 12 volt adapter that I removed from a wall socket

I have a 12 volt adapter that I removed from a wall socket to restore it to 120v. However, the line voltage is only around 60 v rather than the 120 that i need. I have a second 12V wall socket that does NOT have an adapter on it, but it is also showing around 60v. How can I restore the sockets to 120V?

I live in in an old apartment with bad wiring. Most of our 3

I live in in an old apartment with bad wiring. Most of our 3 bedroom apartments outlets go to 1 fuse in the basement, with one of the bedrooms using the other fuse. In the summer, I found that plugging my portable, freestanding air conditioner (the kind with the hose that goes to the window) would lead to that fuse blowing every so often. This would shut the power off for most of the apartment until i ran to home depot and changed out the fuse. It became more and more frequent as the summer went on, and I sold my ac. My question is: is it possible to use a portable ac like before, but avoid blowing the fuse? Is there some kind of voltage transformer/generator/optimizer I can run it through that can reduce the stress on that fuse?Here are some example power specs on the air conditioner:Power and Performance:Capability:CoolingAir Discharge:FrontNo. of Fan Only Speeds:VariableFan Type:Blower wheelRated Amps (Receptacle):15No. of Cooling Speeds:VariableCooling Amperage:6.7Cooling BTU:8000Cooling Wattage:760Heating Amperage:0Heating Wattage:0Maximum Air Flow (CFM):195Voltage:110/120VHeating BTU:0Sound Level (Decibels):Fan Speed, Low - 51/Med - 53/High - 55Thanks for your help.Best,Alex

I was reading by a lamp and all of a sudden I heard a click,

Hi! I was reading by a lamp and all of a sudden I heard a click, lights blinked and that was it. My digital microwave didn't change, nor my TV went off. Just the light. I'm a little nervous about what this was about.JA: I'll do all I can to help. How long have you been dealing with this?Customer: Just today. Never happened before. Nothing happened later.JA: Do you plan on doing the work yourself?Customer: No! I'm an elderly lady and just about know how to flip a switch!JA: Anything else we should know to help you best?Customer: I found the plug was partially out of the socket and I have a cat that was wandering around. Could this be the plug just partially out of the socket that would cause something like that?

I am replacing a wall outlet. It has 2 black wires connected

I am replacing a wall outlet. It has 2 black wires connected via push-in connectors on the back. It has 2 white wires also via push-in connectors on the back. However, there is a third white wire connected through the screw post on the same side as the other white connectors (silver screws) - this wire is HOT and on a separate circuit breaker. How should I connect the replacement receptacle?

I have a portable air conditioner & and a dehydrator that

I have a portable air conditioner & and a dehydrator that both state never to use an extension cord. My understanding is that most extension cords may not be up to the power demands of these appliance. I was wondering if there were extension cords that are made to have to same abilities of a wall socket so that I could use those extension cords even if they are more expensive.My next alternative is hiring some to replace the appliance cords themselves with longer versions, but I thought I'd ask if a "beefier" extension cord was an option.Thanks,Tyler
