UN suppliers are expected to refrain from offering employment to any such person based on the Secretary-Generals bulletin ST/SGB/2006/15. The LCCA should be performed early in the design process while there is still a chance to refine the design to ensure a reduction in life-cycle costs (LCC). As of March 2011, the European Committee for Electrotechnical Standardization (CENELEC) requires the use of green/yellow colour cables as protective conductors, blue as neutral conductors and brown as single-phase conductors.[2]. Over the next hundred years the word mail began to be applied strictly to the letters themselves and the sack as the mailbag. Many local rules and exceptions exist per country, state, or region. For some postal services the sale of stamps to collectors who will never use them is a significant source of revenue; for example, stamps from Tokelau, South Georgia & South Sandwich Islands, Tristan da Cunha, Niuafoou and many others.

The cement production in the USA [] Bus ducts may have all phase conductors in the same enclosure (non-isolated bus), or may have each conductor separated by a grounded barrier from the adjacent phases (segregated bus). For very large currents in generating stations or substations, where it is difficult to provide circuit protection, an isolated-phase bus is used. In buildings with multiple voltage systems, the grounded conductors (neutrals) of both systems are required to be separately identified and made distinguishable to avoid cross-system connections.
