Battlefield V’s creators: female characters are ‘here to stay’ | Circuit Breaker Parts

I think that one of the statements that stuck with me the most while doing LV operations training was from a doctor who said “If you are admitted to my hospital with electrical burns then I will do my utmost to make sure that your family get here before you die”

The customer wasn’t pleased. I had obviously done something wrong. I showed them the paperwork with the specifications showing that the input to the dimmers was to be 20 amps. They insisted that their electrician knew better than I did.

Terminals 4 and 6 are used for capacitors and/or condenser fan connections and have no electrical significance to the starting relay itself, as shown in Figure 1. In fact, terminals 4 and 6 are sometimes referred to as “dummy” terminals and are simply used for wire connections.Figure 2 shows how a potential relay is wired to a capacitor-start/capacitor-run compressor motor. Notice that the relay coil is wired in parallel with the start winding and the start capacitor.

You probably knew that, so I apologize if I’m going over familiar ground, but for others, it’s worth mentioning.

The key is to reference NEC NFPA 70 Table 310.15(B)(16) to find the ampacity of a conductor and size that conductor according to the MCA listed on the unit label. When this is done, the conductor will be properly sized according to the NEC.

When building my printer, I also didn’t like the then state-of-the-art heated PCBs. Thus, I ordered a bespoke silicone heater mat from China, mains voltage, 400 Watts of heater power. Add an aluminium plate to the top and ground it, and safety will be sufficient. I use an SSR embedded into a wall-wart form factor project case with plenty of snubber circuits. Cons: More expensive than a PCB Pros: Heats up incredibly quickly, reasonably priced, won’t get damaged by prolonged high temperature, easy to make non-life-threatening.

The owners manual for the Clipper Creek unit shown in the picture specifically says not to wrap the cord tightly like shown in the picture. If you do the cord WILL get hot internally even when properly wired during a long charge. It needs that open space to vent heat. The cord will stay cool if coiled properly. Whenever people not knowing otherwise coil the public chargers like that I will loosen them up.

Having a ground helps in the case of appliances with metal cases. If the hot wire comes loose and touches in inside of the metal case, it is shorted to ground which will trip a breaker. Otherwise the metal case would become hot which is obviously dangerous. Soil resistivity has nothing to do with it and in fact it would be safer if it wasn’t tied to physical ground, that is just done to save money.

A decent quality electrician’s screwdriver will have its insulation voltage rating stamped on its handle, though the absence of a rating is not necessarily a reason not to use it. A lot of screwdrivers have first-rate insulated handles, but without a voltage rating because they are sold for general-purpose use rather than specifically electronic. When you choose a screwdriver or other tool, consider the amount of plastic it puts between you and the metal, and pick accordingly. Wooden handles may not provide adequate protection, and metal handles should be avoided at all costs.

Actually what they WOULD question is why you’d throw a big power brick on something if you’re just doing resistance heating. Bizarre…

Keep in mind that extension cords running from a generator can power anything that plugs into a wall socket, but not hard-wired appliances such as a furnace, sump pump or central air conditioner. If you want to run any of those during an outage, you will need to have a licensed electrician install a manual transfer switch (it looks like a mini circuit breaker) next to your main electrical panel. A heavy-duty cord from the generator plugs into the switch and allows you to power select circuits in your home. Prices vary depending on your market. In Neale’s case, she paid about $1,200 for the switch and installation, more than for the generator, which cost about $550.

That. Console. Is. Disgusting. Reminds me of my PT Cruiser’s cheapest part: the single piece off-white console.
