Utility voltage of 12.4KV, do I multiply that by square root of 3?

Why would that matter? This forum promotes DIY engineering.

ENE -
Ask away - and learn. Your questions are not out of line with most of the DIY engineering discussed here.



The OP works for a "Lighting, Power and Fire Alarm design firm" - which means they are doing "engineering for hire". They will have to have a PE to sign for ENG's work.

I've never heard of an "over 600V certification" a PE ticket. AFAIK I can stamp anything I want. The state thinks I'm smart enough to know if I should.

Just curious, what are some of the states differing?

I am guilty of not having read the OPs profile to see that he is indeed working as an engineer (EIT), not a contractor. My appologies to ElectricNewEngland for making an ASSumption that you were a contractor. My concerns were based on that issue: a contractor taking on a project that he is not qualified to perform. Here in California, an EC must have a Medium Voltage certificate to work on MV equipment. But as far as engineering it? No; iceworm is correct. As long as a PE stamps it at some point, you are good to go.
