Central-Station Electric Lighting: With Notes on the Methods Used for the Distribution of Electricity
Hedges, Killingworth
Electric light plants -- Europe
“Mr. Hedges points out clearly the risks that are
inseparable from slovenly work and incompetent handling,
and gives clear directions for carrying the main and branch
conductors and the lamp wires, and for calculating the sizes
of the various leads according to the number of lights to be
worked. He insists very properly that some regular system
should be followed, so that it should always be known which
is the positive and which the negative wire,—in other
words, which wire leads from the machine to the lamps, and
which is the return. In addition, however, to showing this
by mere position, _i.e._, by placing the positive wire on
the left side of the negative if vertical, and under it if
horizontal, we should strongly recommend that the insulating
covering should be of different colours on the two wires,
and thus any accidental displacement would not be of
consequence.”

“Ce petit livre sans prétention contient une grande
quantité de renseignements pratiques. Tous ceux qui
s’occupent d’éclairage électrique trouveront grand profit à
le consulter.
“Dans les quatre-vingts pages que contient ce travail,
l’auteur a su rassembler toutes les indications nécessaires
et utiles pour effectuer les installations. Il n’était pas
possible de grouper d’une manière plus logique, plus claire
et plus concise les règles à suivre pour assurer le bon
fonctionnement d’une installation d’éclairage.
“L’auteur s’est étendu surtout sur la description et
l’installation des appareils de sùreté, sur la pose des
conducteurs et sur les diamètres à leur donner, sur l’essai
des circuits, etc....
“Un petit dictionnaire, donnent l’explication des terms
techniques, complète d’une manière heureuse ce petit guide
qui sera consulté avec autant de profit que bien d’autres
ouvrages plus étendus et conçus dans un esprit moins
pratique.
