What does NFPA 70?
NFPA 70E, titled Standard for Electrical Safety in the Workplace, is a standard of the National Fire Protection Association (NFPA). The document covers electrical safety requirements for employees. The NFPA is best known for publishing the National Electrical Code (NFPA 70).
What is the difference between NFPA 70 and NFPA 79?
NFPA 79 – What It Is Said a different way – The NEC (NFPA 70) addresses how that equipment can be electrically installed; but the NEC stops at the outside of the piece of equipment. NFPA 79 picks-up INSIDE the equipment and addresses HOW the wiring and grounding of the actual piece of equipment is done.
What is ul508a?
UL 508A is the UL standard for the construction of Industrial Control Panels. This document gives guidelines to panel builders on various issues including proper component selection, wiring methods and calculation of short circuit current ratings.
What does NFPA 99 stand for?
Health Care Facilities Code
NFPA 99 establishes criteria for levels of health care services or systems based on risk to the patients, staff, or visitors in health care facilities to minimize the hazards of fire, explosion, and electricity.

What are the color codes for electrical wiring?
These high-voltage connections are quite common in many manufacturing and other industrial areas. Due to the serious potential for deadly electrocution or other issues, getting these color codes right is essential. Phase 1 – Phase 1 wiring should be brown. Phase 2 – Phase 2 wiring should be orange.
Do you need color coding for wiring in Canada?
The following requirements on wire color codes apply in Canada: Most narrow wires are color-coded by the manufacturer using different color insulation. If the cables are larger than #6 AWG, they are usually covered with black insulation. During installation, color coding should be added using colored insulation tapes by wrapping it around the wire.
Which is the international standard for control panel wiring?
The EN codes supersede the old British Standards (for the time being, at least) and the international standard EN 60204-1 specifically governs Control Panel Wire Colour Codes.
Why are there different wiring methods for different machines?
Because every type of machine has unique requirements for wiring methods, operator safety depends on your understanding the differences between rules in the NEC and methods outlined in NFPA 79.Every type of machine has unique requirements when it comes to operator safety.
