Many facility managers and contractors face a common question: &#8220;Don&#8217;t these devices do the same thing?&#8221; The answer reveals a fundamental truth about electrical protection. Grounding, GFCI (Ground Fault Circuit Interrupter) or RCD (Residual Current Device), and surge protection devices each address distinct failure modes in your electrical system. They&#8217;re not redundant; they&#8217;re complementary layers that protect against different threats. A properly grounded system won&#8217;t save your equipment from lightning-induced voltage spikes. A surge protector won&#8217;t prevent someone from being electrocuted by a ground fault.
