This protects machinery, and is often good enough to prevent hurting people. </p><p>The GFCI / RCD breaks the <a href="/wiki/Electrical_circuit" title="Electrical circuit">circuit</a> when it detects an imbalance of only 0.005 amps (0.030 amps in Australia and some European and Asian countries). Even this small amount of current, 0.030 amps, going through one <a href="/wiki/Human" title="Human">human</a> body might possibly kill, by <a href="/w/index.php?title=Cause&action=edit&redlink=1" class="new" title="Cause (not yet started)">causing</a> <a href="/wiki/Paralysis" title="Paralysis">paralysis</a> of skeletal <a href="/wiki/Muscle" title="Muscle">muscles</a> and stopping the <a href="/wiki/Heart" title="Heart">heart</a>. </p><p>A standard <a href="/wiki/Circuit_breaker" title="Circuit breaker">circuit breaker</a> protects the house electrical wires, receptacles and <a href="/wiki/Switch" title="Switch">switches</a>, and appliances and fixtures from dangerous conditions, which could contribute to overheating and possible fire. A GFCI / RCD protects people from shock and <a href="/wiki/Electrocution" title="Electrocution">electrocution</a> and is often found in bathrooms or kitchens where electrical devices may be used near water. While using electrical devices in these locations, someone's bare skin may be in contact with water or a wet floor or metal fixtures. Any of these can provide an alternate path for current to travel in the case of an electrical fault. </p><p>A GFCI / RCD can also prevent dangers from short circuits and other electrical faults that don't involve humans such as a low current short where the current never reaches the trigger point for a circuit breaker, e.g. a live wire falls in a tub of water or moist soil and only 1 or 2 amps of current flow. </p> <div class="mw-heading mw-heading2"><h2 id="Types">Types</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Residual-current_device&veaction=edit&section=1" title="Change section: Types" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Residual-current_device&action=edit&section=1" title="Edit section's source code: Types"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>GFCIs are available in two types: the <a href="/wiki/Circuit_breaker" title="Circuit breaker">circuit breaker</a> that <a href="/wiki/Installation" class="mw-disambig" title="Installation">installs</a> in an electrical panel, and the <a href="/wiki/Electrical_outlet" title="Electrical outlet">receptacle</a> type that installs into an electrical box. </p> <div class="mw-heading mw-heading2"><h2 id="Regulations">Regulations</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Residual-current_device&veaction=edit&section=2" title="Change section: Regulations" class="mw-editsection-visualeditor"><span>change</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=Residual-current_device&action=edit&section=2" title="Edit section's source code: Regulations"><span>change source</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>GFCIs are a suitable replacement for two prong outlets without a grounded wire.
