NOTES:          It is important to emphasize that while the NEC and CEC now recognize the Zone classification of hazardous locations, the allowed wiring methods have not changed to those used in many other countries which follow the IEC standards.

For more information on the NEC changes see Mike Holt pages.

For a comparison of US, UK and European methods, see 'three wiring methods used worldwide'.

If you would like to provide information for this page or links which contain relevant information on TECK, Tray Cable, MI, other Hazardous Location rated cable or EMT, please communicate to e-mail address at the bottom of this page.

Comments on effect of changes to 501 for the NEC would also be welcomed.
