Electrical Load List and Earthing and Lightning Protection
We deliver electrical engineering covering load lists, earthing, lightning protection and explosion protected equipment design
Electrical Load List and Earthing
and Lightning Protection
Electrical engineering for process facilities covers far more than power distribution. Inadequate earthing contributes to static ignition in hazardous areas, undersized lightning protection causes equipment damage and ignition risk, and incorrect explosion protected equipment selection creates non compliance that is expensive to remediate after construction. Our team delivers electrical engineering from the load list through single line diagrams, IEEE 80 earthing design, IEC 62305 lightning protection and full IEC 60079 explosion protected equipment selection, all integrated with the hazardous area classification drawing.
Electrical Load List and Earthing and Lightning Protection workflow
Identify all electrical loads, assign operating/starting duty, demand factors, and power factor by system.
Develop SLD covering switchgear rating, transformer sizing, cable routes, and fault level calculation.
Design earth grid per IEEE 80, calculate step and touch voltages, specify earthing conductor sizing and test points.
Conduct risk assessment per IEC 62305, determine protection level, design LPS with down conductor and SPD specification.
Review area classification drawings, select Ex category, protection concept, and T class per IEC 60079 for each installed item.
Support earthing continuity tests, lightning system inspection, and Ex equipment certification registry.
Every deliverable from basis to handover
Complete Electrical Load List and Earthing and Lightning Protection scope covering every calculation, drawing, specification, and construction support activity.
