Probably not. My dad, a licensed electrician around that time of his life, and the contractor buddy he grew up with, built the house over 50 years ago. I've been living in it full time over 34.
Copper oxidizes. And this makes a bad contact, when two wires, or wires and connectors, join. A slightly bad contact heats up just a bit, which in turn increase the speed of oxidation, which then becomes worse and worse. You notice this first by plugs becoming warm to the touch, then hot, then melting the plastic.
A contact that was made 50 years ago may by now not be that good, even if it was perfect at the time. Specially if the connection is not isolated from air.
House 50. Receptacles 22. https://en.wikipedia.org/wiki/1993_Storm_of_the_Century put water up to doorknobs, so all below that level had to be changed at that time. I opened up this one to look today, because most I changed from ivory to white at the time in part to help me track which got done or not, and this was ivory. Connections here were nice and tight and copper and plating shiny, but I changed it to a new white one anyway. Printer is still squawking about half the time, the rest of the times just its relays clacking. Maybe the printer needs some break-in time to draw less initially. :-p
http://www.ebay.com/itm/181010423753 says the outlet in question is good,
That thing does not test for cable resistance, which is the possible issue.
same as all others I've ever tried it in. Had there been a problem when a licensed electrician did my service upgrade from 60 amp and buss fuses to 100 amp and breakers 27 years ago, such problems if there were any should have been found, right?
Not really, they develop.
100 amps... my whole house is 10 amps max, old contract. A typical modern house is about 20A here.
I misremembered. I had upgraded from 120 amp to 200 amp (paired 100A main breakers).
Also FWIW, I live on waterfront.
Does that mean near the sea, lake or river? Sorry, language barrier
Yes. At least part of property boundary touches (usually navigable) water. In this case it's a river close enough to gulf to have occasional salty tide backflow, depending on wind, tidal strength and springs volume.
here. If the humidity is high, or worse, salty, the oxidation worsens.
Humidity is higher than average, but kept reasonable indoors by geothermal heat pump system.
The printer the new Brother replaced was a MF Canon laser. It never made the UPS squawk.
Means that the power surge is higher.
Which could be defect and cause to return it, hence the sub-thread question. I have a new UPS on the way. If the printer does cause the new and/or others to do the same, I may pursue the subject with Brother instead of ignoring it. I don't do a lot of printing, the relays don't bother me, and the beeps don't always happen. -- "The wise are known for their understanding, and pleasant words are persuasive."
