3.3各電路及裝置的尺寸
各條接線和有關之防護裝置之級別

以“用電設施安全條例”及CEI為準。各條電線纜已根據固定電流和短路電流的各種條件中可以接納的最大電流級別和有關的電壓降而制定出各種尺寸。
防護性的各種裝置應擁有一項延伸直至低壓總配電箱足以切斷等，如超逾50KA及對其餘電箱而言的10KA的能力。

結果 (英文) 1:

3.3 the circuit and device sizeAll wiring and related protective devices of level"The facility safety regulations" and CEI prevail. Each wire under constant current and short-circuit current can be accepted in the various conditions of maximum current level and associated voltage drop and the development of various sizes.Protective devices shall have an extension until the low-voltage consumer unit to cut off, such as exceeding 50KA and for the remaining boxes of 10KA capability.

3.3 size of each circuit and device
level of the individual wires and related protective devices of the "power facility safety regulations" and CEI prevail. Pieces of electrical cable is fixed according to current conditions and short circuit current of admissible maximum current levels and associated voltage drop developed a variety of sizes. Various protective device should have a low-voltage main distribution box extends up enough to cut and so on, such as the ability to exceed 50KA and the rest of the electrical box in terms of 10KA.

3.3 the size of the circuits and devicesThe level of each connection and related protection deviceTo "use the electrical facilities safety regulations" and the CEI as the standard. Each wire cable has been based on a variety of conditions of fixed current and short circuit current can be accepted at the maximum current level and the relevant voltage drop to develop a variety of sizes.The protection of all kinds of devices should have an extension until the low voltage distribution box is sufficient to cut off and so on, such as ultra more than 50KA and the rest of the electrical box in terms of the capacity of 10KA.
