Electrical wiring planning and earthing solutions
Create an installation that is correctly sized, logically routed, clearly identified and testable—from incoming supply and earthing to the final outlet.
How safe wiring is built
Wiring and earthing that protect people and equipment
Correctly sized cables, separated routes and a tested earth let protection devices trip quickly when something goes wrong.
- 1. Size the cablesCable sizes matched to each circuit’s load.
- 2. Separate routesPower and data kept apart to avoid interference.
- 3. Build the earthEarth pits and bonding for a low-resistance path.
- 4. Test and recordEarth resistance and insulation tested and logged.
Choose the earthing
Which earthing does your site need?
Soil, load and sensitive equipment decide the earthing design.
Maintenance-free
Chemical earthing with stable resistance.
- Offices and IT rooms
- Stable year-round
- Little upkeep
Dedicated IT earth
Separate clean earth for sensitive gear.
- Servers, CCTV, telecom
- Reduces noise and damage
- Bonded to main earth
System planning
Plan cable routes and circuits before walls close
Good wiring is a coordinated design of loads, conductors, containment, protection, separation, access and testability—not only a choice of wire brand.
Home wiring
Lighting, socket, appliance and essential circuits planned for safety and practical use.
Commercial fit-outs
Distribution, workstations, equipment, lighting and service routes coordinated across trades.
Dedicated technical loads
CCTV, network racks, UPS, automation and sensitive equipment circuits planned appropriately.
Verified selection points
What Zerolink confirms before quotation
Exact specifications depend on the selected product, capacity and system architecture.
Load and circuit scheduleEvery major load is classified and assigned to a suitable circuit before cable selection.
Cable specificationConductor size, insulation type, current capacity, voltage drop and installation condition are checked.
Containment and routingConduit, trunking, tray, bend radius, pulling access and separation from data services are coordinated.
Earthing assessmentElectrode, conductor, bonding, continuity and measured performance are reviewed for the installation.
Identification and accessCircuits, junctions, panels and termination points are labelled and kept maintainable.
Electrical testingRequired continuity, insulation, polarity and earthing checks are completed before handover.

Frequently asked questions
Questions about Wiring & Earthing
Clear answers to common planning and selection questions.
Why is good earthing important?
Earthing gives fault current a safe path, so protection devices trip quickly. It protects people and sensitive equipment like CCTV, routers and computers.
How is an earth pit tested?
Earth resistance is measured with an earth tester after installation and during maintenance, and recorded for future checks.
Can network and power cables run together?
They should be separated or shielded to avoid interference and for safety. Zerolink plans separate routes and containment.
Planning new wiring or correcting an old installation?
Share drawings or book a site survey for load planning, routes, protection, earthing and a scoped bill of quantities.
