The grounding kit gathers the components of a complete electrode: copperweld rod, connector, bare copper conductor, ground-enhancement compound and inspection box, to comply with NTC 2050 article 250 and RETIE. The design target is a maximum of 25 Ω per single electrode (NTC 2050, 250-84).
TECTUL's complete grounding kit brings together the main components to execute a grounding point according to design: Copperweld rod, connector, bare copper cable, conductive cement and inspection box. It is a practical purchasing solution when the project does not require each component to be acquired separately or when maintenance needs to replace a complete point with material traceability. It differs from the Copperweld rod page because here only the electrode is not quoted; conductor, connection, soil enhancer and inspection access are also considered. It differs from conductive cement because the enhancer is only one of the elements in the assembly. The final composition must be confirmed with drawings, conductor gauge, rod length, box type, soil conditions and the electrical responsible party's criteria; therefore it is quoted according to design and not with a published fixed price.

| Rod-to-cable connector | Qualified bond of conductor to electrode (UL 467) |
| Bare copper conductor | Electrode conductor to the ground bar |
| Enhancement compound | Lowers soil resistivity (IEC 62561-7) |
| Inspection box | Access for periodic measurement and maintenance |
Resistance is verified with an earth tester by the fall-of-potential method; if the electrode exceeds 25 Ω, NTC 2050 requires additional electrodes spaced at least 1.8 m apart.
It is quoted according to design, quantity and included components. TECTUL does not publish a fixed price because the kit may change by cable gauge, rod, box and accessories.
The rod is the electrode. The complete kit groups rod, connector, bare copper cable, conductive cement and inspection box when the project requires them.
It is installed according to the electrical drawing: electrode location, cable connection, enhancer application if applicable, inspection box and final system measurement.
The actual description mentions Copperweld rod, connector, bare copper cable, conductive cement and inspection box. The final composition is confirmed when quoting.
Yes, it can be used in industrial and commercial installations as long as the components match the grounding design and site measurements.
Yes. TECTUL dispatches to Bogotá, Medellín, Cali, Barranquilla and other Colombian cities according to availability and transport conditions.
With an earth tester using the fall-of-potential (three-point) method: two auxiliary stakes are driven in line and the electrode under test is measured — the measurement that supports the installation's RETIE certification.
Only if it measures 25 Ω or less (NTC 2050, 250-84); otherwise electrodes are added in parallel, spaced at least 1.8 m apart, until the design value is met.
