Preparing Your Site for a High-Voltage Inspection: What Wassenaar Inspecties Will Ask of You
If you are planning a high-voltage inspection, good preparation can save time, prevent delays, and help the inspection run safely and efficiently. Many clients know they need an inspection, but are less sure about what they must arrange on their side. That uncertainty can create avoidable issues on the day itself.
This guide explains what Wassenaar Inspecties will ask of you before, during, and after a high-voltage inspection. You will also learn how the inspection process is approached, what documents may be needed, what access should be available, and how to support a smooth follow-up if serious findings are identified.
Wassenaar Inspecties helps businesses with inspections in the field of electrotechnics, including inspections of electrical installations, electrical equipment, solar panels, and more. Every inspection is carried out thoroughly and according to applicable guidelines, followed by independent advice and a clear report with findings.
Why preparation matters for a high-voltage inspection
A high-voltage inspection is about more than checking boxes. It supports:
- Technical safety
- Compliance with applicable standards and safety requirements
- Legal and insurance-related obligations
- A clear understanding of the condition of your installation
Proper preparation also helps the inspector work without interruption. That matters because electrical inspections depend on safe access, accurate information, and a controlled working environment.
Wassenaar Inspecties is experienced in inspecting electrical systems and equipment and works with qualified inspectors, modern equipment, and software. The company also focuses exclusively on inspections, which supports an independent and objective assessment.
What Wassenaar Inspecties does during an inspection
Before looking at your responsibilities, it helps to understand what you can expect from the inspection side.
Wassenaar Inspecties explains how it inspects business assets such as installations and tools and what customers can expect from its working method. Inspections are carried out thoroughly and according to applicable guidelines. After the inspection, the team provides independent advice and sends a clear report. An official report is also drawn up by the inspector.
That means your preparation should aim to support three things:
- Safe access to the installation
- Availability of required documents and permissions
- Efficient follow-up after findings
Before the high-voltage inspection: what you need to arrange
The most important preparation happens before the inspector arrives. This stage sets the conditions for safe and efficient work.
1. Complete and sign the Inspectierapport
Before any inspection takes place, Wassenaar Inspecties sends the client an Inspectierapport. This form must be filled in and signed.
This is important because it gives permission for work to be carried out at the location and in the fusebox. Without that preparation, the inspection process may slow down unnecessarily.
What to do:
- Review the Inspectierapport carefully
- Complete all requested details
- Sign the form before the inspection date
- Make sure the form is returned on time
2. Prepare technical documentation when relevant
For a SCOPE 12 inspection, Wassenaar Inspecties would also like to receive several technical documents, if possible:
- Legplan
- Stringplan
- Ballastplan
- Constructieberekening
These documents help the inspector assess the installation more efficiently and understand how the system has been designed and arranged.
If your site includes solar-related systems and a SCOPE 12 inspection is planned, gathering these documents in advance is a practical step that can make the inspection process smoother.
3. Ensure access to the fusebox and inspection areas
Access matters. During an inspection, the fusebox should not be blocked from entry.
This sounds simple, but it is one of the most common preventable issues on inspection day. If materials, stock, furniture, or other obstacles block the area, the inspector may not be able to work effectively or safely.
Checklist before arrival:
- Clear the area around the fusebox
- Make sure the inspector can reach all relevant installation points
- Check that locked rooms can be opened if needed
- Inform on-site staff that an inspection is scheduled
4. Plan around expected waiting and scheduling time
The estimated waiting time for an inspection depends on the size of the installation. If you have 1 or 2 fuseboxes, the estimated waiting time is usually around 3 weeks.
That makes early planning worthwhile, especially if your inspection supports compliance, insurance conditions, or internal maintenance planning.
Practical tip: book early if your inspection is linked to a deadline, a handover, or a scheduled audit window.
During the high-voltage inspection: what Wassenaar Inspecties expects from you
Once the inspection begins, your role becomes simpler but still important.
1. Do not interfere with the inspector's work
During an inspection, it is advised that the client does not interfere with the work of the inspector.
This helps the inspector maintain focus, follow a safe process, and complete the inspection efficiently. Electrical inspection work requires concentration and a controlled environment.
That does not mean you cannot coordinate with the inspector. It simply means the work area should remain orderly, calm, and free from disruption.
2. Keep access routes open
The fusebox and relevant installation areas should remain accessible throughout the inspection.
Even if access was clear at the start of the day, daily activity on site can change that. Deliveries, tools, temporary storage, or staff movement can create new obstacles. A quick internal check can prevent disruption.
3. Be available for operational questions
Wassenaar Inspecties is open Monday to Friday, from 09:00-17:00, and is available to help with questions regarding its services and to guide clients through the inspection process.
On inspection day, it is useful to have a responsible contact person available who can:
- Confirm access
- Answer practical site questions
- Assist with permissions if needed
- Coordinate any internal communication
This does not mean standing beside the inspector all day. It means making sure support is available if required.
What equipment may be used during inspection
Depending on the type of inspection, Wassenaar Inspecties uses different equipment.
SCOPE 8
For SCOPE 8, the equipment used is:
- FLUKE 1664
- MEGGER MFT-X1
SCOPE 10
For SCOPE 10, the same tools are used as for SCOPE 8, with the addition of thermal imaging using:
- FLIR E60 camera
- HIKMICRO V2 camera
SCOPE 12
For SCOPE 12, the equipment used is:
- HT INSTRUMENTS PV-CHECKS
- EAZYPV
All instruments are properly calibrated on time.
For clients, the key takeaway is simple: the inspection is supported by professional tools suited to the inspection type. If you are preparing for related inspections such as SCOPE 8, SCOPE 10, SCOPE 12, NEN 1010, or NEN 3140, it helps to understand that different systems may require different test methods and access conditions.
After the high-voltage inspection: what happens next
Preparation does not end when the inspector leaves. What happens after the visit is just as important.
1. Review the report carefully
After the inspection, Wassenaar Inspecties provides:
- Independent advice
- A clear report with findings
- An official report drawn up by the inspector
This report gives you a structured basis for any next steps. Because the company focuses only on inspections, its assessment is positioned as independent and objective.
2. Resolve serious findings with an external company
If the inspection identifies a serious finding, the customer is expected to resolve the issue with an external company.
Wassenaar Inspecties does not position itself as a party that benefits from recommending unnecessary repairs or work. That separation supports an objective inspection role.
3. Return the Herstelverklaring
After repairs have been completed, the customer is expected to send the Herstelverklaring back. This allows an inspector to check whether the repairs were carried out correctly.
This follow-up step is essential. It closes the loop between inspection, correction, and verification.

Practical takeaways for a smooth inspection
If you want the inspection to go well, focus on these essentials:
- Handle paperwork early. Complete the Inspectierapport before the visit.
- Prepare access. Keep the fusebox and work areas free and reachable.
- Share technical documents. For SCOPE 12, provide the requested plans if available.
- Minimize disruption. Let the inspector work without interference.
