TīmeklisAn Arc Flash typically releases between 5 to 30 calories and energies of 30 to 60 calories are not uncommon. Most Arc Flash injuries can be prevented if proper Flame Retardant (FR) PC & PPE is worn. The problem with non FR clothing is that during an Arc Flash, the high energy ignites the non-FR clothes, which causes body burn … Tīmeklis2024. gada 4. nov. · Re: Setting flash voltage. The ESP-WROOM-32 chip is used. In common case (external 3.3V is used on GPIO12 in the circuit) flashing is not possible, the flash is blocked. But, in case I connect GPIO12 temporarily to GND during flashing and also during device's start, everything is OK.
