When necessary to avoid obstruction, a side or offset arm . may be used. In all 6l1oh cases a s.peolal arm of the same dimensions as the standard arm shall be used. This arm shall 'be bored for pins and belts and installed with an angle-iron brace. Wherever a transformer is used on any such pole on which side-arm construotion is used, an idle arm shall be pro... -~ vided. .--.-.'-,'-..-"'''-. . 70 standard practice; provided, this shall not be held to apply to electrical machinery and auxiliary devioes carrying six hundred volts or less.
