Abstract: In allusion to the problems such as the altitude circumscribed conductor terminal less than required value, irregular equipment N and PE rank usage existing in the routine detection of low-voltage switchgear assembly. This paper presented the standard parameter requirements and considerations in the installation technology, and several kinds of waterproof measures in the waterproof testing, which provides references for avoiding this type of problems when the enterprise manufactures this sort of switchgear assembly products in the future.
Key words: low-voltage switchgear assembly; installation technology; standard; waterproof
