  • I used one of these cheap plugs for installing my MIL’s EV charger before I heard of the issues. However, It’s been fine because I under-utilized it due to the continuous load. I’m using it on a 40 amp circuit (code allows for this, as there is no 40 amp receptacle, so these plugs are allowed in this situation) with a 40 amp breaker and the charger is set to “40 amps”, which is really 32 amps, via dip switches, so it’s drawing 80% of 80% of 50 amps.

    Given the problems I’ve heard, though, I might just change it up and just hard wire it, even if I’m almost certainly fine anyway.

    Almost nobody actually needs a 50 amp charger, unless you’re driving something like a Hummer EV. As long as you’re charging at 230V, a 15-20 amp draw is PLENTY for 99% of situations. Even at that lower amperage, most cars would charge from close to dead to 100% in less than 12 hours and the majority of people only discharge above 60-70% on their daily commute. Even a 110V 15 amp outlet can handle charging that overnight.




  • It does have some excellent use cases. Asbestos tile was probably everywhere you walked in school, is extremely durable, and perfectly safe (unless you cut it with a saw). My house is covered in asbestos siding and is basically unphased in appearance since it was installed in 1964 by the Texas sun.

    However, any situation where it can cause it to be airborne, such as brake pads, insulation, etc. is no bueno. It’s a kind of incredible material IN VERY SPECIFIC USE CASES.

    Like most materials science, there are tradeoffs. R22 was a great refrigerant compared to R410a or the newer R32 that required way less pressure to be effective, but it also burned holes in the atmosphere, hence it isn’t used anymore. Asbestos is an incredible material, but so is flurooantiminic acid and I wouldn’t want it anywhere near me.
