ELECTRICAL INSTALLATIONS.

AT HOME AND HEBE; An interesting departure in the matter of- electrical installations is reported in an engineering supplement to (he London "Times" of May 12 last. It concerns systems of electric wiring, in regard to which the Wellington City Council vainly attempted somo time ago to arrive at n,u understanding with the New Zealand Underwriters' A&acintion. Tho London "Times" reports that after two years' work by an Knjjlish permanent committee,' upon which all , interests were represented, official -recognition has been given to modern developments in electrical installations, and Hint it is hoped that revised Tulcs, which have s-ccured the adherence of the leading insurance cum]>uni?s, electricity supply companies, and municipal"elrctricnl a-;ociatio:i<,' representing two hundred Kudisii municipal authorities, will stand without revision for at lea.-t !ivo years. The advantage

springing from the now regulations, (lie "Times" Mates, will ln> t!i:tt a class of wiring not liiihoilo oftioially roeoenUed, will be made available l.>r general use. Formal recognition ha* K-cn areai'dod to the large iimoiiiil of wiiik done on "llexiblc" system--. Tin- il-o of them lias b.'on hedged with llio ro.-trictiaiis, and their oinjilnymcnt for llio iirst time placed upon a piMjiov lia>is. Uroopni-tion-lias also been accorded to otlier now forms of wiring, lir. Jl. Cable ias>isla.nt city 'eloctrieal encinrer) told a reporter ycNierdny thnt systems of "swl'acp wiriiif!" advoralod some lime ago bv the local lißliting ilep.irdnont are fiilisfanlially iilontical vvAi tlioso which have now, in UiißlaiuV, obUiincd the inthiential otlicial sanction and recognition indicated. The. , resistance of the Undrvwrilers' Assacialifln lias hitherto prevented the adoption of the new wiring rule; in Wellington, and the facts Miggesr. Mr. Cable remarked, that New Zealand, in this matter, is tagging brhindtho times.

In reference, to the Mr. P. Richardson (oily olcctriral cnsjincor) told a reporter ytv-teylay that as soon-as the ■full text of Hip revised wiring rules came from England (hoy would ho adopted in Wcll-iiiston. The present Gorman ivirins rules. Mr. Kiehardsou rpmarked, differ considerably from those liilherto enforced in England, and which have been also observed in Xotv Zealand. The Germans permit a much smaller fize of wire to bo used for a crivon number of lamps Ihnn _is nivA in England, and, generally sppflkilifr, Eiipland has l»pn very consprvntivc in thopo matters as comphifd with flermany. ]n I'liicland a certain sot. ol rule* has lioen rplipionsly adliorpd to, althnu!»h in the jiipaiitiine electrical in-: Ftallotions of all kinds have undo crrat pri'srcp-. flermany, on Uip eonti;iry, has lcept. , of iinp.revpmi'nls, and oilopioil ils rules to modern refiuirpinenls. From Hip eonsnnipr's poinl of view lli<> important benefit arising from the ndnption of new rules would lie a considerable reduction in •{'■■• e.i-t: of (•}??■ trieal ■ insl.illations. >r. liiolnrdsnn dialed (hat until lie had seen Ihr- full lexl of the new rules ho pniiM not s,« how erf at tin's savin* would he.
