Construction Sites
In the UK, electric tools and portable lighting at construction sites are increasingly required to be fed from a centre-tapped system with only 55 V between live conductors and the earth. This system is used with 110 V equipment and therefore no neutral conductor is needed. The intention is to reduce the electrocution hazard that may exist when using electrical equipment at a wet or outdoor construction site. An incidental benefit is that the filaments of 110 V incandescent lamps are thicker and therefore mechanically more rugged and shock-resistant than 230 V lamps.

Famous quotes containing the word construction:
“No real “vital” character in fiction is altogether a conscious construction of the author. On the contrary, it may be a sort of parasitic growth upon the author’s personality, developing by internal necessity as much as by external addition.”
—T.S. (Thomas Stearns)
