ECN Forum Forums General Topics of the Trade General Discussion Area Simple question about voltage and current ratings

Dear all,

I am new to the industry and new to this forum. So thanks for bearing with me on a simple question!

When a 3-phase electrical box, eg this one is rated at 400A, does that mean 400A per phase, or 400A total i.e. 133A per phase?

Also, this box for example is rated as 600V - does that mean phase to phase, or each phase to neutral?

Many thanks!!
