In general, BS 7671 applies to circuits supplied at nominal voltages (Uo) up to and including 1000 volts AC or 1500 volts DC. The standard therefore covers the Extra Low Voltage (ELV) range (0-50V AC, 0-125V DC), and the Low Voltage (LV) range (50-1000V AC, 125-1500V DC). The frequencies covered for AC are 50 Hz, 60 Hz, and 400 Hz, used in the UK for houses, offices, and commerce. It did not become a recognizedBritish Standarduntil the publication of the 16th edition in 1992. The standard takes account of the technical substance of agreements reached inCENELEC.

Rutland (/ˈrʌtlənd/) is a landlocked county in the East Midlands of England, bounded to the west and north by Leicestershire, to the northeast by Lincolnshire and the southeast by Northamptonshire.
Its greatest length north to south is only 18 miles (29 km) and its greatest breadth east to west is 17 miles (27 km). It is the smallest historic county in England and the fourth smallest in the UK as a whole. Because of this, the Latin motto Multum in Parvo or "much in little" was adopted by the county council in 1950. It has the smallest population of any normal unitary authority in England. Among the current ceremonial counties, the Isle of Wight, City of London and City of Bristol are smaller in area. The former County of London, in existence 1889 to 1965, also had a smaller area. It is 323rd of the 326 districts in population.
The only towns in Rutland are Oakham, the county town, and Uppingham. At the centre of the county is Rutland Water, a large artificial reservoir that is an important nature reserve serving as an overwintering site for wildfowl and a breeding site for ospreys.
Rutland's older cottages are built from limestone or ironstone and many have roofs of Collyweston stone slate or thatch.
