Green Eggs and Blam!

By | Conduit

Prior to the 2018 version, NFPA 70E simply cautioned that “greater emphasis may be necessary with respect to de-energizing” equipment with incident energy (IE) exceeding 40 cal/cm2, “when exposed to electrical hazards.” This nebulous direction was applied within the industry by simply labeling everything over 40 cals as “Dangerous – No PPE Exists.” In its new 2018 version, NFPA 70E eliminated this cautionary language. This may lead some to infer that working on energized equipment…

Playing Zone (Interlock) Defense? Consider This in Your Game Plan

By | Conduit

While ZSI may be an effective way to mitigate risks of injury and damage to electrical equipment in the event of a fault, it must be specified, applied, and installed properly – and thoroughly commissioned. All circuit breakers within the protected zone must be equipped with ZSI capability. ZSI installation depends on proper interconnect wiring between circuit breakers, and often, different switchgear lineups…

A Cookie Cutter Approach Can Cost You Dough

By | Conduit, uPDate

How often is your standardized approach resulting in an over-designed ground grid? Stop wasting your dough by blindly erring on the side of caution simply because you don’t know what lies beneath. While standardizing a ground grid design seems like it would save time and money, this approach fails to consider a site’s soil composition and resistivity. Soil resistivity is affected by variables such as layer composition, moisture, molecular structure, salt content, other chemicals, etc. Making assumptions based merely on a site’s location, visible soil observations, or soil borings is not enough to determine its apparent resistivity. All variables, especially those affecting life-safety, must be incorporated to allow for site-specific considerations…

A Man, A Ferret, and a Two-Dollar Fix

By | Conduit

Last week, I watched a BMS contractor trying to communicate with a Variable Frequency Drive (VFD), but as soon as he tried to control the VFD’s speed, the connection was dropped. Although both the BMS contractor and the VFD contractor tried for a couple of weeks to resolve the issue with their respective tech support groups, nothing they suggested worked…

Discontinuation of GE Multilin™ SR Relays

By | Conduit, uPDate

GE Grid Solutions is discontinuing several relays from its Multilin SR family of products. These microprocessor-based multi-functional relays were widely used around the turn of the century for industrial protection and management applications in industrial environments, data centers, electrical service entrances, distributed generation (DG) interconnects, motors, transformers, and generators. GE announced, “manufacturing of SR750/760, SR469, SR745 and SR 489 will be discontinued on 1st of January 2020 due to the unavailability of critical components used within the product.” Options for customers with affected relays…
