air conditioner safety questions
I just bought two 5000 BTU air conditioners.
I'll abbreviate them to "AC" if y'all don't mind.
Here's the specs:
I then had a wiring guy connect my 2-prong bedroom outlet to the grounded wire (which he said was already there), thereby replacing the 2-hole plugs with 3-hole plugs.
The air conditioners were then installed in aforesaid bedroom, and also the kitchen (which already had grounded outlets in place).
Thing is, the cord of the bedroom's AC did not quite reach the outlet (note: the bedroom AC is a temp installation and will hopefully soon be relocated within reach of the outlet, once the 50s windows are retrofitted)..
..so for now, I plugged it into this exact 3-ft. extension cord:
...which I then plugged into a heavy-duty TIME-ALL Intermatic 15-amp grounded timer (in order to test the timer which someone gave me, since I want to use the AC with a timer).
Here's a pic of the timer:
The timer was then plugged into the aforesaid bedroom outlet.
I then ran the AC on Low-Cool for an hour (sufficient to see that the timer was working fine).
I then noticed that the timer had become very hot to the touch. So I decided to test the timer via the identical model Frigidaire AC which had been installed in the kitchen window within reach of a long-established grounded outlet.
The problem is, that because:
(1) the outlet is an upside-down configuration (with the grounded holes above the hot/neutral holes)
(2) molding which was frustratingly placed surrounding the upper part of the outlet-cover...
...therefore, I can't test the kitchen AC with the timer, since the molding prevents the timer from plugging in sufficiently to make a connection.
(interestingly, the AC plug does manage to make a connection in that same outlet).
When I tested the kitchen AC with its plug directly in the outlet, the plug remained cool to the touch after running the AC for awhile.
I'm hoping to use timers with both the air conditioners to save on electricity, but running into all the above-mentioned obstances & not sure what to do.
HERE'S WHAT I DID NOT YET TRY:
Testing the bedroom AC with the 3-ft. extension cord plugged directly into the wall (without the timer) for at least an hour. And then see if the plug of extension cord gets hot. I may do that soon, at next opportunity.
But I'd still be left with the question of how to get a timer to connect into my frustrating, upside-down kitchen outlet.
