Frequently

Asked Questions
  1. Q1: Can I have a sample for testing?
    A: Yes, you can, but you need to pay.
  2. Q2: Can I add my logo on the clothing?
    A: Yes, OEM and ODM are available.
  3. Q3: Do you have inspection procedures for the products?
    A: 100% self-inspection before packing.
  4. Q4: Can I have a visit to your factory before the order?
    A: Sure, your visit is welcome at any time.
  5. Q5: How can I get after-service?
    A: We assure 2 years warranty. During this period, If any product quality issues occur, spare parts will be sent for free. But we have to charge if the problem is caused by man-made factors.

The Basics of Arc Flash Fact Sheet v2 - GE Industrial

The Basics of Arc Flash by Cameron G. Clark: GE Specification Engineer Do you know what an arc flash is? If not, keep reading. The goal of this article is to give the reader a basic understanding of what occurs during an arc flash incident, and an understanding of some of the terms used in qualifying the danger associated with such events.

What Are the 4 Different Arc Flash PPE Categories in NFPA ...

NFPA 70E 2018 now gives four categories of PPE, with each category including the minimum Arc Rating value for the required PPE. Discover a brief overview of each of the 4 PPE categories, including the clothing required for each, as well as information on determining which PPE you need to use.

Arc Flash PPE Categories - Oberon Company

An arc flash risk assessment can indicate whether such PPE is needed. The analysis also needs to be documented. PPE is a combination of protective clothing, helmets, goggles, or other garments or equipment to protect eyes, head, breathing, and the full body from splashes, vapors, loose objects, and chemical penetration through personal clothing.

No More Hazard Risk Category 0 - Arc Flash & Electrical ...

Other exceptions may be built on the basis of your arc flash study, equipment design and maintenance level and risk assessment. There are limited instances when <300V (208V 3P is an example) could pose an arc flash hazard when the fault current and clearing time are high, these should be assessed by a qualified engineer.

Calculating Arc Flash Energy Levels EC&M

Where E is the arc flash energy, E n is the normalized arc flash energy, I a is the arcing current, C f is the calculation factor, t is the duration of the arc, D is the distance from the arc to the person (from IEEE 1584, Table 3), X is the distance X-factor, k 1 and k 2 are constants, and G is the conductor air gap.

Calculating Arc Flash Energy Levels Electrical ...

In many cases, a lower short-circuit capacity may produce a much larger arc flash energy level. For this reason, IEEE recommends that the arc flash energy be calculated both at the calculated arcing current and again at 85% of the arcing current (also known as the second-arcing current) and that the higher arc flash energy value be used.

NFPA 70E Hazard Risk Category Levels (HRC)

NFPA 70E Hazard Risk Category Levels (HRC) NFPA 70E is a safety standard that denotes Hazard Risk Categories (HRC) based upon an array of occupational duties. An HRC level is determined by the minimum amount of calories per square centimeter (ATPV or Cal/cm2).

Evaluating NFPA 70E Arc Flash Hazard Category Tables

gram determined a hazard/risk Category Level 3 for the faulted location (MCC-1). This category level agrees with the one listed in the table. A different simulation was performed for the same MCC, but this time using the maximum available bolted short-circuit current of 65 kA. Evaluating NFPA 70E Arc Flash Hazard Category Tables
