Electrical wiring in the United Kingdom lawnmower does it need an RCD?" The risk of electrical shock on construction sites can be reduced by several measures, including reduction of the normal 230 volt distribution voltage to 110 volts for electrical lighting and power tools. By using a centre-tapped transformer, each conductor of the circuit is only at 55 volts with respect to earth. This reduces the chance of dangerous electrical shock when using power tools in wet locations. Where 230 volts must be used, a residual current device (RCD) can be used to detect small leakage currents and automatically isolate faulty equipment. In sites where hazardous
Safeguard Safeguard A safeguard, in international law, is a restraint on international trade or economic development to protect communities from development aggression or home industries from foreign competition. In the World Trade Organization (WTO), a member may take a safeguard action, such as restricting imports of a product temporarily to protect a domestic industry from an increase in imports causing or threatening to cause injury to domestic production. In the United Nations Framework Convention on Climate Change, safeguards are intended to protect indigenous peoples and other local communities with traditional knowledge of natural resource management within efforts towards reducing emissions from
