Tuff shed faulty wiring
I have a Tuff Shed in my yard that I’m currently refinishing, and I need urgent advice about a potentially serious electrical and fire hazard.
The shed has electrical wiring installed by a professional. It has daisy-chained LED ceiling lights and a dedicated 20-amp outlet for a Midea air conditioner.
A couple of weeks ago, I had the air conditioner running when it suddenly stopped connecting to or responding through the phone app. I went outside to investigate and tried unplugging the AC from the outlet. The plug was extremely difficult to remove, and I had to pull very hard before it finally came out.
When I removed it, part of the plastic surrounding the outlet broke from the force of pulling. It felt as though the plug had melted or fused to the outlet. I also saw black, burned discoloration on the AC plug’s metal prongs and around the inside and outside of the outlet. Everything felt very hot, including the plug and its prongs.
These are signs of overheating, arcing, melting, or another electrical fault that could start a fire. I immediately turned off all of the breakers—there are only about three—in the breaker panel inside the shed. They have remained off ever since, and I have not gone back into the shed.
For safety, I will keep the power off. I will not reset the breakers, enter the shed to use the electrical system, plug anything in, or attempt to replace the outlet or troubleshoot the wiring myself. I will contact a licensed electrician as soon as possible and have them inspect the entire circuit before anything is repaired, reset, or reused. The electrician should check the outlet, plug, wiring, breaker, connections, and air conditioner for damage and determine the cause of the overheating. The damaged outlet and plug should not be used again.
If there is currently any smoke, heat, a burning odor, sparking, flames, or other active danger, I will stay away from the shed, keep people and pets away, and call the fire department or emergency services immediately. I will not approach the shed or breaker panel if doing so is unsafe. If the breaker panel cannot be safely accessed or I cannot confirm that the breakers are off, I will not approach it and will contact emergency services or a qualified professional for guidance.
Can anyone explain what may have caused this and what needs to be repaired or replaced? How serious is the fire risk, and is there anything else I should do while waiting for a licensed electrician?
I’m not sure whether it is related, but there was also a thunder and lightning storm the night this happened.
Thank you for any advice!
