How to ground a distribution box that has no grounding pin
The most common and simplest solution for an ungrounded circuit is to install a Ground-Fault Circuit Interrupter (GFCI) device. Electrical grounding is a fundamental safety mechanism that provides a low-resistance route for fault current to return to the source and trip a circuit breaker or fuse. This pathway prevents metal casings of appliances and tools from becoming energized with hazardous voltage during an internal. Especially for low-power devices, such as routers, mobile phone chargers, small lamps, and so on. I am exploring a way to install an outdoor outlet out of my main electrical panel but I couldn't find any visible ground bar (s) that the ground wires (in green color) can connect to, nor do I see a ground wire somewhere attached to any bars at all other than one that got attached to a bonding. It's a common scenario that can leave even the most seasoned DIY enthusiasts scratching their heads. That little red tail under the cable clamp means you have BX or MC feeding that box, that metal jacket is your ground.
