You can find out roughly how old your wiring is by simply looking at it. If the wiring around your fuse box is covered in old-fashioned casing, or is damaged or fraid, it may be over 25 years old and need replacing. This is more common in older properties or houses that have been empty for long periods of time.
Isle Of Scalpay
Scalpay is an island in the Outer Hebrides of Scotland. Scalpay is around 4 kilometres (2.5 miles) long and rises to an elevation of 104 metres (341 feet) at Beinn Scorabhaig. The area of Scalpay is 653 hectares (2.52 sq mi). The main negotiation on the island goes to the north, near the bridge, clustered around An Acairseid a Tuath (North Harbour). The island is peppered with little lochans. The biggest of these is Loch an Duin (Loch of the Ft) which has a tiny island in it, with the remains of the fort still visible. Eilean Glas, a little peninsula on Scalpay's eastern shore, is home to the initial lighthouse to be constructed in the Outer Hebrides. Scalpay's nearest neighbour, Harris, is simply 300 metres (980 feet) away throughout the narrows of Caolas Scalpaigh. In 1997, a bridge from Harris to Scalpay was developed, changing a ferry service. In 2001, the island had 322 individuals, whose main employment was fish farming and prawn angling. By 2011 the population had declined by 9% to 291 whilst during the same period Scottish island populations in its entirety grew by 4% to 103,702.
