2 electrical questions in the interview
Thread Content
During the interview, the employer asked me two questions related to electrical safety. I would like those who are experts in this field to answer them: 1. What standards are followed for temporary electricity use at construction sites? What type of standard is it – a national standard or an industry standard? And what is the minimum height required for the temporary power lines installed there? 2. For the AC arc welders used at construction sites, what are the difficult aspects to check when conducting inspections (please explain in detail)?
Your requests are too detailed. Asking such questions in an interview… It seems like they’re all related to the content covered in the constructor certification exams. I suggest the original poster buy a book on the constructor qualification exams. There’s also the Technical Code for Safety in Temporary Electricity Use at Construction Sites, which is basically based on JGJ46-2005. Here’s a website you can check out as well: Temporary Electricity Use Plans for Construction Projects: http://www.jgzj.net/bbs/archiver/tid-249104.html
I actually think the question he asked is quite reasonable; after all, details determine success or failure, and by looking at some more detailed questions, one can assess a person’s knowledge and expertise!
One more thing: GB50194-93 Code for Safety of Power Supply and Use at Construction Sites
