I have a customer wanting to use our equipment in Russia. They'd be using a single phase 20A circuit. I understand they use 230V, 50 Hz. Do they have a grouned neutral, as we do here in the US? In the US, we rely on the neutral being grounded, so we don't fuse it (since a neutral short to ground does not create a fire hazard). So, what is the power configuration in Russia? Anyone aware of a website that shows schematically electrical standards throughout the world (single and three phase, from the final distribution transformer(s) to the customer load, including standard placement of grounds, fuses, etc)? Thanks!
