Electrical Safety and Consequences of Ignoring It
Tuesday, February 7, 2012
Electricity is so ubiquitous in our loves we often (mostly) take it for granted. "Haven't died yet," is the basic underlying theme. But that can come back to bite you. Hard. Where it hurts. I recently had an event that, while somewhat embarrassing, is worthy of sharing to illustrate a point that might save you.
The real damage was done when this heat, over the four of five hours the machine was running, transferred into the digital timer which was plugged into the outlet. The heat melted the current-carrying wires inside.
First step was to get a "real" protection device. I settled on the Tripp Lite Ultrablok428. With a 15amp rating, its metal enclosure and standard NEMA type outlet, it is advertised as having an "Indestructible all-metal housing [that] won't crack, burn or melt." As you can imagine, that caught my eye, along with, "10,000 Dollar Ultimate Lifetime Insurance and lifetime product warranty." It plugs directly into the wall outlet and comes with a bracket that keeps it from being accidentally unplugged. It was one of the few I found rated at 15 amps. It also leaves the other wall outlet available as seen here after I installed it:
But what to do about the damaged timer. I had bought two when they were being closed out at our local Grocery Outlet, so I plugged the spare into the wall until the Tripp Lite arrived. But the base of the damaged timer where it plugs into the outlet had melted so badly it was no longer usable. I opened it and there was quite a bit of damage and the odiferous aftermath of toasted wires filled the air. Hmmm... But it was still working- at least the timer and clock were. So here's what I did:
I took the main board which held the battery backup as well as the relay and related electronics that operated the circuit to turn the controlled device on and off and mounted that in an old multi-outlet, industrial two-gang box seen above.
(A) is the 5-lead control wire from the main board to the control head
(B) is the power feed and plugs into the Tripp Lite Ultrablok
(C) is the DD's power cord plugged into a switched outlet
(D) I removed one of the duplex outlets and that left plenty of space inside for the electronics and wiring. The hole left from the removed outlet was covered with something I had saved and seemed quite appropriate.
But how to deal with the control unit? It was off to the thrift store.
I found a gooseneck reading lamp,
removed the lamp portion at the end of the neck,
and here's what I ended up with.
So, a moral - It should be obvious. If you are using a high current-draw appliance, it is not only best to isolate it on its own circuit if possible, but be sure that if using extension cords or a surge supressor of any type, be sure that they are rated to handle the current. I got lucky in that there was no fire, and when it failed I was home to deal with it. Don't rely on luck.
