What is IEC code 287?

Going underground with a medium-voltage or high-voltage installation? What size conductor do you need?\n\n"For many underground applications, you can find ampacities in cable manuals, says Axel Schlumberger, technical marketing manager for Forte Power Systems™. "For specialized installations, or for high-voltage, you'll need a calculated answer."\n\n\nGoto http://www.stormcopper.com/design/Buss-Bar-Ampacities.htm\nThe basis for most high-voltage underground ampacity calculations worldwide is an international standard, IEC 287. IEC 287 covers medium-voltage and high-voltage cables, many different constructions, and many installation types. Just as the Neher-McGrath method to calculate ampacities is the predominant method used in the U.S., IEC 287 is the predominant method used internationally. Both methods are employed through the application of thermal equivalents of Ohm's and Kirchoff's Laws to a simple thermal circuit.\nThermal Resistances Determine Ampacity\n\nIEC 287 uses a thermal resistivity circuit model of the cable installation.\n\n12R losses in the conductor, dielectric losses in the insulation and eddy currents in the sheath all generate heat. Cable materials and soil represent a series circuit of thermal resistances. The thermal resistances control heat dissipation from the conductor. If you dissipate more heat, you can carry more current.\n\nThe key element in the series heat circuit is the external thermal resistance outside the cable. Here are some factors.\n\nSoil thermal resistivity. How well does the soil carry away the heat? Soil resistivity is a specialized measurement. If you don't have actual numbers for your site, many handbooks -such as the EPRI Underground Transmission Systems Reference Book - give design assumptions.\n\nAmbient soil temperature. Warm soil absorbs less heat.\n\nInstallation depth. It is assumed that the heat finally goes to the ground surface. Deeper cable sees more total soil resistance.\n\nInstallation method A direct-buried cable generally dissipates heat more readily than a cable in a duct.\nNearby Cables Complicate Heat Flow\n\nAdjacent cables contribute heat and may induce additional losses in the cable itself. Closer cables have more effect.\n\nSheath grounding makes a difference. Multipoint grounding increases circulating currents in the sheath. Single-point grounding eliminates sheath currents, but away from the ground point, induced voltage on the sheath has to remain within certain limits.\n\n"If you have an underground installation that can't be sized with standard ampacity tables, check with your cable vendor," says Schlumberger. "With high-voltage in particular, you may need assistance with the calculations."

What kind of circuit breaker are you looking at?  Is this abreviation associated with numbers?\n\nSome manufacturers have product line codes -- could this be it?  For instance, Square D has types HOM, CO, A1, EDB, EGB, etc. etc.

If you are in the US, there is a building codebook that has tables for all wire sizes and their ratings.  Its called the NEC handbook

EN8 is not a valid code. Checked www.royalmail.com and TomTom. There is EN80 but not the one you are after i'm afraid.
