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 Coaches route to Westborough and then to Park Barn, and the Guildford Park service reached Dennisville. In 1988, Farnham Coaches was purchased, adding a significant number of vehicles to the Safeguard fleet. In 2000, Safeguard gained the contract for the Guildford Shuttle, a free service connecting various parts of Guildford Town Centre. At first, a Plaxton Pointer bodied Dennis Dart SLF was acquired. This was replaced by an Optare Alero. However, this proved too small and so another Mini Pointer Dart was acquired. More recently, in 2002, Safeguard lost some school bus work and Onslow routes 10/11 to Countryliner after ten
