If a consequence is human death then obviously that is completely unacceptable. If it blows a fuse at 1000V then good! If traces vaporise disconnecting the mains at 10,000Votls then well done! Where is the weakest point (lowest creepage clearance for the exposed voltages) and what are the consequences of a flash over at that point.
Actually what they WOULD question is why you’d throw a big power brick on something if you’re just doing resistance heating. Bizarre…
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)

@ [Martin] DC can kill you hours later because it goes through your body like lightning, it takes the path of the lowest resistance (usually the most moist path) and cooks everything in it’s path including vital organs.
On Demand Refrigerant Safety Classes A2L and A3 have a very low GWP, making them a strong, long-term solution for many HVACR applications. However, these refrigerants are classified as mildly flammable and highly flammable respectively. This flammability class raises safety and compliance concerns. This webinar will help you understand these classes, along with the opportunities these refrigerants can offer.
Cooking Triac? In my experience there are only good Triacs and bad Traics. You can tell the bad Triacs because they usually have a a little bit of plastic encasing still attached to the three legs after they have exploded.
I adore the Gravity Blue finish on this tester â it’s a welcome change from the sea of grey, silver, and white that fills every damned parking lot. More blue/green here again.
A clean filter is vital to a well-functioning air conditioner. During the summer it is good to check your filters once a month. If you have pets, leave windows and doors open, or have allergies, you may need to change your filter more often.
No need, really. You just need a few mates with smartphones – just enable the wifi hotspot on each of them, place them roughly in a circle and put your coffee in the center. Make sure to dismantle the circle before you reach in for your cup though if you don’t want to get fried too – safety first!
400 Hz is the frequency of choice for aviation. That’s why the PA system in airplanes has *that* particular background tone in it.
Nah, they’re just creating the latest OpenSource platform as Arduino LCC, Arduino iso, Arduino Inc and Arduino & Co. fight over which is the real Shady.
