Electrical testing and installation acceptance.
Acceptance and periodic tests, independent installation acceptance, photovoltaic PV systems, earthing and lightning protection.
4BIT performs measurements and technical assessments of installations in houses, flats, commercial premises, industrial facilities and public buildings.
Service scope
From visual inspection and testing to a report and technical assessment.
Earthing and LPS
Earth resistance, equipotential bonding and testing of lightning protection systems.
Photovoltaic PV
Visual inspection, AC and DC tests, and assessment of PV protection and switchgear.
Installation acceptance
Independent verification before taking over an installation or settling the contractor's work.
Periodic inspections
Houses, premises, property managers, commercial, industrial and public facilities.
Documentation
Clear test reports, result schedules, descriptions of defects and recommendations.
Electrical installation testing
Acceptance and periodic tests matched to the facility.
We test electrical installations according to the type of facility, supply arrangement, protective measures and the purpose of the inspection.
- fault-loop impedance measurements
- insulation resistance measurements
- continuity of protective conductors and equipotential bonding
- testing of RCD residual-current devices
- earth resistance measurements
- testing of lightning protection systems
- verification of electric-shock protective measures
- visual inspection of switchboards and installations
- preparation of measurement documentation and reports
The test scope is selected for the installation, facility and purpose of the inspection.
Photovoltaic PV
PV system testing together with the building's electrical installation.
A photovoltaic system is part of the building's electrical installation and requires proper verification of its technical condition and protective measures.
- visual inspection of the PV installation and cable routing
- verification of protective bonding and earthing
- assessment of installed protective devices
- AC-side testing
- DC circuit testing within the scope permitted by the system and the measuring method
- assessment of AC/DC switchgear
- preparation of a test report
Basic PV system testfrom PLN 600
PV + AC + earthing + protectionfrom PLN 900
House testing + PV systemfrom PLN 1,200
Large PV system / business facilityindividual quotation
The DC-side scope depends on the system design, accessible test points and functions of the instruments used.
Electrical installation acceptance
Independent technical assessment of houses and other facilities.
In addition to measurements, we can assess workmanship, protective devices, available documentation and compliance with the adopted technical solutions.
The acceptance scope may include
- visual inspection of the installation and switchboards
- verification of protection, RCDs and surge protection
- assessment of protection against electric shock
- verification of earthing and equipotential bonding
- assessment of the lightning protection system, where present
- required electrical tests
- assessment against available documentation
- identification of observed defects
- preparation of acceptance documentation
