NEN 3140 inspection of electrical installations

Unnoticed defects can cause fire, injury or downtime. Want your electrical installation inspected? With a NEN 3140 inspection, we assess the risks and identify any necessary corrective actions.

From inspection and measurements to corrective action

Not every defect in an electrical installation is visible. That’s why our inspectors combine a visual check of distribution boards, cables, earthing and switching devices with measurements and tests. For example, we check the insulation resistance and the operation of residual current devices. In addition, thermography enables us to detect overheating in distribution systems. 

Before we begin, we determine which installation parts will be inspected and coordinate any required power-down periods with your operations. Once the inspection is complete, you’ll receive a report outlining the identified defects, categorised by priority, along with an action list for remedial work. Our in-house electrical specialists can carry out these repairs for you. This gives you clarity on what needs attention and allows you to have us resolve any issues as well. 

  • Visual inspection

    During the NEN 3140 inspection, we check distribution boards, cables, earthing and switching devices, for example, for damage, correct application and fire safety.

  • Measurements and testing

    Our NEN 3140-certified inspector carries out tests, such as for insulation resistance, continuity, impedance and residual current device operation. 

  • Clear reporting

    You receive an inspection report in which we clearly categorise any defects found by priority, so you can get started straight away.

  • Inspection and rectification

    Have any defects to your electrical low-voltage installations been identified? We can take care of all repairs, thanks to our own in-house Facta specialists.

Frequently asked questions

What does an NEN 3140 inspection for low-voltage electrical installations involve?

We visually inspect an existing low-voltage electrical installation according to the NEN 3140 standard and carry out a range of measurements and tests. In addition, we can also use thermography for a more detailed inspection.

When is an NEN 3140 inspection important?

The NEN 3140 inspection determines whether employees can safely work with or near electrical installations. We also identify potential causes of fire, faults and downtime. 

What happens after the inspection?

You receive a clear inspection report detailing our findings. We also provide an action list for any necessary remedial work, which we can carry out with our own specialists.

Can you also repair identified defects?

Yes, we can also repair and resolve any issues identified during the inspection. Ask us about the options and we will be happy to provide you with a clear quotation.
