AFCI circuit breakers and the problem of ‘nuisance tripping’ | Circuit Breaker Parts

Level 2 charging systems come in two basic varieties, plug-in portable and wall-mounted units that are hard-wired directly to a home’s electric service. If you don’t have a closed garage and you’ll be charging the vehicle outside, local codes may require a fixed-mount unit. Otherwise a portable charger requires no professional installation, assuming you’ve added the 240-volt service line. This type can come in handy if you own two homes or will be staying with friends or family in another town and want to take the unit along for charging at your destination.

#PreferLinux mentioned switching off at the mains socket. Do that, but still test; that saved me once when the switch was faulty. Yes, that socket was replaced, pronto!

It also doesn’t hurt to spend a bit more. I found a 40A SSR, well-known Japanese brand, from a reputable distributor, for $30. That said, I might easily have made this same mistake; thankfully I won’t have to learn the hard way (this time!).

I think that’s technically just thin graphite. Graphene is 1 molecule thick sheets. People were gobsmacked when they discovered you could make it with sellotape.

Of course you can use an extra 50Hz transformer, you do not need voltage regulation. But you need power (DC) for motors and electronics. If you have already a switching PSU (which are often even cheaper than big heavy iron/copper transformers of the same power) the extra power capability for the heater does not cost very much. Lets say you will not get the 120VA transformer for the price difference of lets say a 80W PSU vs. a 200W PSU. Also you can switch the DC with a single MOSFET.

For transient rise times of 0.1 to 0.2 μs, twice the unit value of surge capability is required on stator windings. When rise times reach 1.2 μs or greater, 4.5 times the unit value is stipulated. In the case of external transients such as lightning, this would equate to a surge voltage capability of 918 VPEAK for a 230-V motor (full load current = 12 A) on a 250-V high-line condition. (Lightning surges can exceed these values, so stator windings would also need a suppression element for protection.)

This certainly looks like one of the more impressive ARM-powered Windows 10 laptops we’ve seen so far. The first few devices ran on the same Snapdragon 835 chip found in Android smartphones from last year, and they showed early promise with some issues that still needed work.

This plate is too likely to touch the user. It’s sensible to have a certain fear of mains voltages, makes you pay attention when you’re working with it. The DC power suggested would come from the printer’s existing PSU, pay a little bit extra for a few more amps, the overall wattage isn’t high. Much less than I presume you’d use in industry. Thanks to power-hungry graphics cards, high-power PC PSUs are cheap.

You like many others here can wallow in their own baseless opinions, meanwhile millions including myself very safely charge up using 120 volts almost every night. I usually use a higher voltage for the BOLT, but the ELR mostly just charges on 120 the same as most VOLTS.

120V comes with a nice plug (NEMA 5-15P) that is smaller than EU’s and you can fit more of them onto a power bar. There are always two outlets in a wall receptacle. Unless you have wet fingers, 120V won’t kill you (usually). Ask most kids that stuck things in the wall outlet and have lived to tell their tale… it is very common. Aluminum wire for branch circuits in homes was all but banned three decades ago or more. I think you have embellished things a bit. Look up the history why Europe went 50 Hz, instead of a higher frequency like 60 Hz… your lower 50 Hz results in heavier transformer cores. Find out why Japan is 100V, and the country is split 50/60 Hz! There is always politics, and not pure technical reasons.

In the old days, we were always careful to remind readers to purchase a second battery along with their camera, but in recent years, battery life has become much less of a concern than it once was. Not so with the Sony A33, though: Unless you intend it only for light snap-shooting, consider the purchase of a second battery mandatory.
