Is mem breaker a rcd

A clever question!

A "mem breaker" is not a type of RCD (Residual Current Device), but rather a colloquialism or a meme that has gained popularity online.

A "mem breaker" is a humorous term used to describe a situation where someone shares a shocking or surprising fact, joke, or story that "breaks" or shatters the expectation or assumption that someone had. It's often used to describe a moment of surprise, revelation, or "aha!" that leaves someone speechless or stunned.

On the other hand, an RCD (Residual Current Device) is a type of electrical safety device that is designed to detect and interrupt residual currents (i.e., currents that flow to earth) in a circuit. RCDs are commonly used in electrical installations to provide protection against electrical shock and electrocution.

So, while a "mem breaker" might be a fun and unexpected surprise, it's not a type of RCD!
