AMP Seeks More PJM Scrutiny of TO Projects | Circuit Breaker Parts

If you’re buying an EV, make sure the power outlet or wall-mounted charging station will be located within close proximity to your vehicle’s connecting port. Charger cables usually run from around 15 to 25 feet in length, but that may not be sufficient or desirable if the car’s port is located on the opposite end of the garage from the available power source. You may have to have an electrician extend the service closer to your car’s charging port if that’s the case.

I really do like the C-Max, as it’s a compelling value, and it actually drives fairly well in my opinion.

Low voltage DC distribution makes sense in some cases. 12V is pretty low, though: copper losses are still high, so the amount of copper required is expensive for house-scale. 48V uses one sixteenth the amount of copper, and still is below the shock hazard limit. 48V rack systems are mature, common and are a great idea.

The potentially game-changing performance of the Sony A33′s EVF overshadows its excellent rear-panel LCD, which is a little unfair: It’s as good an LCD as is found on any other camera, and in at least one sense literally outshines them all. It’s the same widescreen ~920K-dot high-resolution LCD we’ve seen now on a wide range of cameras from a variety of makers, but its implementation on the Sony A33 adds a couple of useful twists. First, of course, it literally twists and rotates, albeit from the bottom of the body, rather than the side. This unfortunately makes it useless for composing self-portraits with the camera mounted on a tripod, but otherwise is quite helpful for getting over-the-head and ground-level shots with ease.

Here I have always wondered. If the power bill is such a concern, then why not buy a heat pump for water heating instead? (It drawn typically around half to a third of the power to give the same heat output.)

Step 3: Use the pulse-rating curves (Fig. 2) in the same datasheet to determine pulse capabilities relative to the 40 pulses at the 1000-A requirement.

Dude routinely welds wearing shorts and flip flops. He’s also known to weld quite a bit of galvanized steel, as he does in this video with the lifting ring. Not saying he should do any of this, but there it is.

The contacts therefore return to their normally closed position by spring power as the motor coasts to a stop.

For the sake of simplicity in this example, assume the objective is to select a low-voltage dc disc MOV for the following circuit conditions and requirements:

Just reach for the “Flame Wrench” while working on a press, in a corrugated box plant. Within the next two minutes, you’ll know how many fire extinguishers are in that building. Box dust and the old, grease based, Letterpress ink was always a major concern when you were doing the repairs and needed to use a grinder, torch or welder, etc..

The standard in UK is 230 V not 240 V, like the the rest of the EU. The continent was mainly using 220 V until 1986 and UK 240 V until 1986. The 230 VAC was choosen by the IEC as a compromise between the 220, 230 and 240 system. So actually main voltage in EU should be 230V +/-6% at distribution panel, and equipement should support 230V +/-10%. (voltage drop in the internal house distribution should be less than 4%) But a transition period of 20~25 years was used, during the transition period main voltage at distribution panel in UK should be in the 230 VAC +10%/-6% range, and in the rest of EU it should be in the 230 VAC +6%/-10% range. (Other 240 VAC country like Australia and NZ switch to 230 VAC at least officialy)

True, but I have never seen a product use them. They will probably become popular with wifi powered stuff.
