各位大虾,! c0 ?, {# `5 P+ e: o
在GB 494-2001的2.6.3.2中明确说用于测试的电流额定值是取以下最小值:
( h2 ^7 F2 R+ m6 X( } ——设备的额定电流;
! u- W" L' x; l+ @7 X7 r/ f3 ^ ——建筑物配线中的过流保护装置的额定值;3 I, B" x+ w/ n
——设备中过流保护装置的额定值。6 K* S/ ^9 e6 Y& ^( Q, H! f! W
....... 七楼已经说得很明白了:6 z* j$ ~% e: _! ?0 k1 l
以下是摘录标准内容,在CB报告中测试电流应该为16A的1.5倍.
- E- u5 @8 g. q% `# fa) For PLUGGABLE EQUIPMENT TYPE A, the PROTECTIVE CURRENT RATING is the rating of an! z( H& ]# k0 T4 L

NOTE 1 In most countries, 16 A is considered to be suitable as the PROTECTIVE CURRENT RATING of the circuit.

NOTE 3 In the United Kingdom, the current rating of the circuit shall be taken as 13 A, not 16 A. |
