Do you need to supervise or carry out low-voltage electrical work independently? The B2 B2V electrical qualification is mandatory for a work supervisor who performs de-energized work and intervenes in the vicinity of live bare parts. Compliant with France’s standard NF C 18-510 and labor code requirements, it certifies mastery of electrical safety rules for performing electrical work alone or supervising a team of electrical workers.
Issued by the employer after B2V electrical qualification training completed with a training organization, it validates an operational skill level for working safely and supervising workers on site.
The standard recommends recertification every 3 years; in practice, most companies make it mandatory to maintain skills and compliance.
Discover throughout this guide the B2 / B2V training and assess your need to follow this type of electrical qualification training.

What is the B2 B2V electrical qualification and how does it differ from B1 B1(V)?
The B2 B2V electrical qualification is the employer’s recognition of an employee’s ability to prepare, perform, supervise and control low-voltage electrical work, while respecting the prevention measures recommended by Standard NF C18-510. The B2(V) electrical qualification will notably allow:
- Perform independently (without supervision) electrical work on de-energized LV installations (below 1kV in alternating current and < 1.5kV in direct current)
- De-energize a Low Voltage electrical installation for one’s own account
- Supervise a team of electrical workers to perform de-energized LV work (cooperate with the lockout supervisor (BC), manage the work zone, control procedures and bear safety responsibility throughout the work duration)
- Perform the 2nd step of a lockout as part of a 2-step lockout procedure
More specifically, you will be able to perform de-energized work and organize work in the vicinity of live parts, in a controlled vicinity zone (distances, marking, protective equipment).
Definition and B2V symbol

The electrical qualification level B2V specifies the domain and nature of authorized interventions:
- B: low voltage (0 to 1,000 V in alternating current, 0 to 1,500 V in direct current)
- 2: work supervisor (preparation, supervision, coordination of B1/B1V workers)
- V: possibility to work in the vicinity of live bare parts in LV, i.e. in the reinforced vicinity zone, less than 30 cm from an accessible live part (PPE equipment is mandatory within this zone)
Differences between B1V and B2V qualifications
Although both B1V and B2V qualifications concern low-voltage electrical work, they do not correspond to the same level of responsibility or scope of intervention. Here is a clear table to distinguish these two categories:
| Criterion | B1V | B2V |
|---|---|---|
| Role | Low-voltage electrical worker | Low-voltage electrical work supervisor |
| Main function | Perform de-energized electrical work according to received instructions | Prepare, organize, supervise and control de-energized electrical work |
| Hierarchical position in the operation | Works under the responsibility of the work supervisor | Responsible for the team and site safety |
| Authorized intervention zone | Simple vicinity zone (zone 1) and LV reinforced vicinity (zone 4) | Simple vicinity zone (zone 1) and LV reinforced vicinity (zone 4) |
| Nature of tasks | Execution of defined tasks: installation of collective protection, simple handling, compliance with procedures | Intervention management: risk analysis, choice and control of CPE/PPE, coordination with BC |
| Lockout | Performs lockout maneuvers commanded by a lockout supervisor | Coordinates with the lockout supervisor (BC), verifies documents. Can perform the 2nd step of lockout. |
| Documents and procedures | Consults and applies instructions | Drafts/completes documents (authorization, certificate), defines work zone limits |
| Responsibilities | Cannot have collaborators under their responsibility and cannot work without supervision. | Assumes safety responsibility for the operation and workers |
| Operation examples | Wiring an electrical panel under the supervision of a work supervisor | Supervise a B1/B1V team on electrical work |

B2V training assessment
B2V electrical qualification training assessment is based on two complementary components: a theoretical assessment and a practical assessment, in accordance with standard NF C 18-510 and labor code requirements.
Theoretical assessment (MCQ)
The theoretical part is assessed through an MCQ covering essential concepts: electrical risks, vicinity zones, lockout procedures, symbol choice, effects of alternating current, collective and individual protection devices.
The trainee must demonstrate that they can identify electrical risks and apply electrical safety rules through concrete situations.
To practice, we offer a corrected B2V MCQ test
Practical assessment
The practical part consists of a scenario-based evaluation on representative installations. The trainee must:
- prepare a work zone safely;
- verify absence of voltage (VAT);
- organize grounding and short-circuiting (MALT) if necessary;
- identify the vicinity zone and respect limit distances;
- supervise B1/B1V workers by applying intervention methods;
- implement protective equipment and analyze risks.
The trainer also assesses the future work supervisor’s ability to communicate, supervise a team, make decisions in real situations and respect regulatory procedures.
Post-training assessment
Upon completion of the assessment, the training organization issues a post-training assessment, an essential document allowing the employer to officially issue the B2V electrical qualification.
What are the training formats for B2 electrical qualification?
B2/B2V electrical qualification training can be completed inter-company, within sessions bringing together professionals from different sectors, or in-house, directly at your site to adapt the session to your installations and internal procedures.
For more flexibility, a blended learning format is also offered: the theoretical part is completed through distance learning (e-learning), while the practical part is conducted in-person on a technical platform.
What qualifications can complement B2 electrical qualification?
H0 / H0V
The H0B0 electrical qualification (possibly complemented by H0V) is necessary to operate in environments with High Voltage risks, without authorizing you to work on HV installations. Very concretely, if you must for example work on a Low Voltage Main Distribution Board (LVMDB) located in an electrical room containing cells and an HV transformer: you must have H0 qualification (and possibly H0V if you must operate in Zone 2, HV reinforced vicinity zone)
B2V Testing
B2V Testing electrical qualification is necessary for commissioning an installation after work.
BC (lockout supervisor)
If you are responsible for performing the lockout procedure for your team of workers (or external teams) to work on installations, BC electrical qualification will be necessary. B2V electrical qualification only authorizes de-energizing for one’s own account (i.e., if you are the one who will then work on the installation)
BR (general intervention supervisor)
BR electrical qualification will be necessary to perform General Interventions: detection of failures/malfunctions (which may include measurements), replacement of defective equipment (relays, terminal blocks…), connection and disconnection while energized under certain conditions (max 500 V, 63 A in alternating current and performed without load).
In practice, work supervisors are often qualified B2(V) BR BC H0(V).
H2V (high voltage work supervisor)
B2V equivalent for high voltage (HV). Natural evolution for sites requiring HV operations.
Summary table
| Qualification | Function | B2V Complement |
|---|---|---|
| H0 / H0V | Access to HV/LV rooms for work only in LV | Can be completed in the same training session as B2(V) |
| BC | Lockout (VAT, MALT…) | Can be completed in the same training session as B2(V) |
| BR | Troubleshooting interventions | Can be completed in the same training session as B2(V) |
| B2V Testing | Testing, measurements and verifications after work | Can be completed in the same training session as B2(V) |
| H2V | High voltage HV work | Requires additional 7h training if you have already completed B2V training |

FAQ
FAQ – B2V Electrical Qualification
-
The B2V electrical qualification is valid for 3 years. Beyond that, recertification is necessary to keep skills up to date, and the employer must ensure regular monitoring to verify that the employee maintains the knowledge and practices required to work safely.
-
The electrical qualification certificate is issued exclusively by the employer. Their decision is based on the post-training assessment provided by the training organization as well as the employee’s medical fitness to perform electrical work.
-
Yes. The training can be partially completed remotely: the theoretical part is accessible through e-learning, while the practical part must necessarily take place in-person, on a technical platform, to ensure acquisition of professional skills.
-
B2V Testing qualification includes B2V prerogatives but adds authorization to perform testing after work, making it an essential qualification for commissioning or control activities.
-
No. B2V qualification does not authorize live work. To perform this type of intervention, a specific qualification is mandatory, as technical and safety requirements are much stricter.
-
The choice depends on intervention conditions: if work occurs only de-energized on a fully locked-out installation, B2 qualification is sufficient. However, as soon as there is presence of voltage in the vicinity, B2V qualification should be preferred.
