You are correct and if you design this type of solution you already know this. With PCB design, the alternatives are heavier copper, wider traces, plating up copper in the areas that carry heavy current or a combo of any of the three. But you can only go so far with these solutions. Hack apart a known good SSR and I bet they use the exact same solution.

A good quality EVSE can cost between $300 and around $1,200. If you’re choosing a wall-mounted unit, expect to pay another several hundred dollars for installation, depending on local labor rates and permit costs.

You also need to insure that the hot line is completely isolated from the neutral line other than via the intended switching and power supply paths. Insuring that is a hell of a lot easier when you use registered isolating components to do it.

Many people do not own their own home and must deal with a landlord, who may feel that providing a high-quality 110 volt receptacle for the car to recharge is the end of their responsibility.

There’s a proper place for a relay and a proper place for a SSR. And I agree this solution should have been a relay.

The skin depth varies with the magnetic permeability of the material. Iron for example reacts at very low frequencies, so much so that it becomes useless for wires at 50 Hz.

Add in the approx. 75 cents of AC shore power I pump in every night, and it works out in my head to about 5 cents per mile. Takes a lot of words and numbers to explain that figure, but the practical impact is that every day I drove over two hours, the car bought me lunch. I feel like I’ve patched a hole in my money pocket. This is half the running cost of any other car I’ve owned, including the TDI.

Gardner Minshew II threw two touchdown passes and ran for another score and No. 12 Washington State stopped No. 25…

A steamy day on the flat roof of a building will let you feel how many inches the 480 can sting your fingers from also.

Flake, along with Sens. Chris Coons (D-DE) and Cory Booker (D-NJ), attempted for the second time to schedule a floor vote on the bill protecting Mueller on Wednesday, but it was blocked by Sen. Mike Lee, who argued that the legislation was unconstitutional (a longstanding conservative argument, explained by Vox’s Tara Golshan here). The bill would ensure that Mueller could only be fired by a Senate-confirmed DOJ official and enable the special counsel to review any firing.

The Sony A33 offers a lot of control for shooting contrasty subjects. Dynamic Range Optimizer (DRO) adjusts contrast and brightness to optimize the camera’s use of available dynamic range. Auto HDR modes use three quick shots to cover an amazing tonal range. (The shot on the right represents the maximum range of 6 EV.)

Overall though, if everything is designed so it can’t hurt you, even in far fetched and unlikely worst case scenarios then many things would just never get made. In this case I think you could make a safe heated bed as long as you take safeguards to ensure a low probability of accidental shock. A simple enclosure around the board and the connections would more or less end the shock safety debate. Fire is another issue I guess, probably a fuse would solve that.
