I'm designing control panels that will be shipped to Singapore and installed in a manufacturing facility that is owned by the company I work for. Can anyone offer some suggestions to consider? I'm aware of the wire color differences. Any thoughts on the type of PLC to use? Do the NEC calculations and tables apply?
Thanks,

NEC tables will not apply, but generally the NEC is about safety, so there is nothing wrong with using it. But there will be rules you may not be familiar with, you would need to buy a set of IEC standards to be sure about them, it's too extensive to go into here. For one thing, wire sizes are metric and current ratings are totally different. In addition, you have to contend with the different voltage, frequency and control circuit conventions. lastl;y, and by no means leastly, they likely have much more stringent machine safety requirements than we do here. There are very strict rules about safety relays etc., and although we tend to ignore them here because nobody has a gun to our heads about it (yet), over there they do. You might weant to hire out a machine safety consultant to evaluate your machine (called a Safey Audit) and make suggestions on how to meet thei IEC requirements.

Bear in mind that frequency is 50Hz and single phase voltage is 230V.
Single plugs and receptacles are three pin like those used in UK.

Singapore Electrical Standards

Singapore Electrical Standards

Singapore does have a Code of Practice for Electrical Installations (CP-5), but it would not be applicable to control panel construction. As previously mentioned they do use IEC Standards, there are 15 or 16 that might apply to control panel construction. Siemens has the island cornered as far as the PLC market.
