Peter Walsh joined General Electric Company in 1969 as a Field Engineer. Since then he has seen many electrical incidents in a variety of roles and companies. He began his forensic career with GE supplying analyses to their legal team. His original Professional Engineering status was with NJ in 1975.
He forensically investigated incidents in the proximity of electrical equipment, such as fuses, and provided application assistance for a total of 20 years with the largest fuse companies. Applied electrical products in accordance with National Electrical Code, OSHA regulations, IEEE Standards, and good practices. Trained classes of electrical maintenance people on NFPA 70E, OSHA regulations, IEEE Standards, Surge Protection and good electrical safety practices in commercial and industrial settings.
Peter has provided technical leadership to electrical industry codes and standards organizations. He helped revise NFPA 2008 National Electrical Code as technical committee member of Panel 4. He helped with later editions by proposing additional amendments. He served on other NFPA technical committees such as 110 and 111 and also participated in meetings with NFPA 70E committees. NFPA recognizes him as Electrical Safety Compliance Professional.
Within IEEE, he has served this Standards Organization so long as to obtain Lifetime Membership. Presently he is a technical committee member for IEEE 1584, “IEEE Guide for Performing Arc Flash Calculations”, and IEEE 1814, “IEEE Recommended Practice for Electrical System Design Techniques to Help Improve Electrical Safety”.
OSHA recognizes him as an “Authorized Trainer” for General Industry. He focuses on training electrical maintenance people.
He has written numerous articles about arc flash, arc flash calculations, surge arrestors, and general electrical industry equipment.
