MOVs tend to degrade gradually after a large surge or multiple small surges. This degradation leads to increasing MOV leakage current; in turn, this raises the MOVâs temperature, even under normal conditions such as a 120-V ac or 240-V ac operating voltage. A thermal disconnect adjacent to the MOV (Fig. 4) can be used to sense the increase in MOV temperature while it continues to degrade to its end-of-life condition. At this point, the thermal disconnect will open the circuit, removing the degraded MOV from the circuit and thus preventing potential catastrophic failure.
Did your kitchen light stop working soon after the closet light? Did you change a light switch last month? Facts about recent electric changes in your home could lead me in the right direction, so it’s helpful if you can list them up front. (Don’t miss these 41 secrets home inspectors won’t tell you.)
The control buttons are for the most part intelligently arranged and readily accessible, but the small space available for them on the right side of the body does mean that you need to hold the camera in your left hand to be able to access them properly: They’re really too close to the right side of the camera to keep your fingers wrapped around the grip and operate the buttons with any degree of comfort. On the angled top/back panel, the EV adjust button is perfectly located, right under your thumb, with the AE lock and movie recording buttons on either side of it. The movie button does require a deliberate reach to get to, but is nonetheless easy to identify by feel when you’re looking through the viewfinder; just slide your thumb over until it hits the viewfinder housing, and you’ll be right on top of the movie button.
No, thatâs not a typo in the fact box up top. I drove the Niro PHEV a total of 253.2 miles, and topped off the tank with 3.107 gallons of regular unleaded. 81.4934 miles to the gallon very nearly doubles the mileage I observed last year in the standard Niro. 26 miles of all-electric range makes a serious difference â there were many days where the gasoline engine never fired.
Viking if your cord is getting hot, it’s being overloaded. Time to upgrade the circuit wiring and breaker. The cable doesn’t necessarily have to feel cold, but it shouldn’t feel noticeably warm to the touch either.
many years ago I had the bad behaviour to strip cables using my teeth… well, one day I was ready to strip the end of a cable that used to connected to my portable stereo (240v), its just few seconds that I noticed that the other end was still plugged-in on the mains…
It does seem to be an old electrician’s habit, never leaving the leads plugged into amps. Somebody commented on one of Big Clive’s videos about him doing that. Seems like a good habit to get into.
As always, in terms of refinement, petrol or diesel drivers need to recalibrate their minds, not least because the near silence (bar wind noise) below 2000rpm stands in contrast to the engine noise that intrudes thereafter. At a cruise the peace is notable, while if you push on the arrival of engine noise is a momentary surprise rather than a permanent irritation. A sub-8.0sec 0-62mph time underlines that this is a reasonably pacy hatch too.

In addition to working at Structure Tech, he is also a licensed Truth-In-Sale of Housing Evaluator in Minneapolis, Saint Paul and several other cities.
If he ever turns his car on its side so that the car jack is pointed toward ceiling and plugged into the evse as shown, then I’d worry about it.
1. Metal-oxide varistors (MOVs) are available in a variety of form factors and sizes for a broad range of applications. The radial leaded disc type is the most common version.
MOVs are rated for specific ac-line operating voltages. Exceeding these limits by applying a sustained abnormal overvoltage condition could result in overheating and damage to the MOV.
