IS 732:2019 — Electrical Wiring Installations

Code of practice for electrical wiring installations, relevant when coordinating lightning protection with the building electrical system, service entries, protective measures and wiring arrangements.

SN Engineering use: This is an original engineering summary for project understanding. It does not reproduce the purchased standard. Final design must use the applicable official standard edition, project specification and authority requirements.

Why it belongs in the lightning-protection library

External LPS design interacts with internal electrical installations. Wiring, protective devices, service entry, bonding and earthing need coordinated review.

Use with NBC and SP 30

NBC 2016 electrical services and the National Electrical Code of India reference/align with applicable wiring and earthing standards. The lightning-protection page should link these documents rather than pretending IEC 62305 replaces electrical-installation rules.

Final engineering package

The electrical designer should provide SLDs, service-entry details, major equipment, sensitive loads and existing protective-device information for SPD/bonding review.

Project Implementation Checklist

For an actual project, record the applicable standard edition, risk-assessment assumptions, approved drawings, selected design method, calculation revision, component specification, inspection/testing requirements and final engineering approval.
