An enhanced type of a transformer major reduce-out made toprotect the higher-tension side of transformers is becoming introduced bythe Westinghouse Electric &amp Manufacturing Business. It is madeentirely of porcelain, and its kind is such that it has high insulatingand arc-breaking qualities. The plug to which the fuse is attachedprojects between the terminals, the upper end of it rising nicely intothe top of the block and interposing an eflfective barrier, and thusmaking it not possible to preserve an arc. The fuse is eleven inchesin length, making a long break, and is so placed that the vapors ofa discharge are blown down and out of the device and away from theterminals. The line wire is carried straight to the best of the device and at-tached to it as to an ordinary insulator, which it as a result displaces.

A bend in the fusewire brings it into plain view at all instances, and it is hence attainable toobserve its condition with no removing the plug, guarding againstany liability of opening the circuit when there is a existing upon theline.

Favor 12 Gallon Tank as Common The thought of standardizing on a 13 gallon tank forelectric homes, suggested in a current problem by Mr. S. H. Ex-cell of Vernon, B. C, has met with considerable favor. Hereare a couple of letters from electric merchants: Ottawa, Aug. 11.Editor Electrical News, Relating to H. S. Excells suggestion for 12 gallon watertank for household use. We are of the opinion that the 12gallon tank would be a lot more advantageous from an economi-cal point of view, and would give enough hot water for or-dinary each and every day use. It would also reduce the cost of in-stallation. Standardizing on the 12 gallon electrically heatedwater tank would be a step in the appropriate path.Yours truly, P. E.
