Is my appliance compatible with the Amazon Smart Plug? | Circuit Breaker Parts

L2 is absolutely useful in cold climate, specially when you don’t have a heated garage. Because a very minimalistic L1 level won’t be able to charge much while also having to keep the battery at a functional temperature, more less to preheat the car or the battery at optimal temperature.

Agree on stupidity, but psychopaths have gotten an undeservedly-bad rap. See this: http://www3.nhk.or.jp/nhkworld/en/tv/firstclass/201604140600/ I’m proud to say that I scored 19 (average-level psychopath) on the the quiz that was presented.

Coastal BC might be viable for them, here in the “temperate” bit of Ontario they’d be good in April and October.

In the case of an opto-couple my ‘rule of thumb’ is for the min to be the distance between the pads on left and right rows of pins. ie nothing under the opto at all apart from the pads connecting the pins.

Getting reasonably priced SSRs that are trustworthy seems almost impossible. A 40A TRIAC costs $34. I know there’s more than the TRIAC in the SSR, but it’s not like there are that many components either… I end up using relays if at all reasonable and scratch my head when they’re not…

I will not put all the money on the bet, but this one might be indeed one of the solutions: http://www.mouser.com/ds/2/328/lnk302_304-306-179954.pdf if you want something “all-in-one”. I prefer a separate external PSU for many reasons, including circuit separation and protection. You can find 5V and 3.3V SMPS DIN rail mouting ones for decent prices.

You may be confusing voltage drop ALONG a power line with the voltage BETWEEN lines. Maximizing the latter will transmit same power with less current, minimizing the first and hence Ohm’s Law power loss through transmission.

In the above, the first was the result of a fault condition making a sub part of the internal chassis float at HT voltage. The second was the result of a “friend” jokingly giving my shoulder a shove when I was working.

I certain the Residual Current Circuit Breaker is what GFCI is in North America. Not expensive at all for the units that will fit into a device box. The breaker that mount in the breaker panel are pretty pricey though, but are rarely called for. The only time they are needed if a building uses shallow device boxes for some reason.

Jamie Spinelli’s job as a case manager for Community Services Northwest takes her to parks, homeless shelters, the jail and…

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.

If a high-frequency current is large enough to be immediately painful, it’s large enough to immediately burn you, which is why hooking a tesla coil to a doorknob is rather dubious. It hurts, because it really hurts.
