The Registered Professional Electrical Engineer shall have recent experience in performing power system studies.

1. SCOPE OF WORK

The Service Provider should furnish an Arc Flash Hazard Analysis per NFPA 70E Standard for Electrical Safety in the Workplace, reference Article 130.3 and Annex D; based on the formulas found in IEEE 1584 or equivalent, and satisfying the requirements of OSHA 29 CFR 1910.132(d).

This study will apply to only three phase equipment rated 240 volts or greater and three phase equipment rated lower than 240 volts when served from a transformer 125 kva and larger unless an expanded scope of services is selected by ABC Corporation.

Work shall include:

1.
