Free Practice Questions for Habilitation B2V/BR

A B2/B2V is a chargé de travaux who organizes and supervises teams of B1/B1V executants, with V covering reinforced vicinity. A BR performs short-duration, localized general low-voltage interventions, may carry out mise en sécurité for that intervention, and may direct one B1 assistant. The 63 A AC limit applies to specified connection or disconnection in the presence of voltage; it is not a blanket maximum for every de-energized BR operation.

Article R.4544-10 makes the employer responsible for issuing the title and defining its scope. The employer considers competence, the role-adapted theoretical and practical training opinion, assigned operations, and environment. B2V and BR also require the five-year occupational-physician attestation of absence of medical contraindications under the rules effective from 1 October 2025. The employer sets validity; INRS recommends refresher training about every three years for ordinary operations.

No. Under NF C 18-510, electrical consignation for planned works is the exclusive responsibility of the Chargé de Consignation (symbol BC). The B2 receives an 'Attestation de consignation pour travaux' from the BC before commencing any work. However, the B2 is responsible for verifying that consignation has been completed and, if not performed in their presence, conducting their own Voltage Absence Check (VAT) on the work site.

The 5 distinct steps in chronological order are: 1. Séparation (isolation from all power sources with a visible break or positive contact indication); 2. Condamnation (locking the isolating device in the open position with padlocks and warning signs); 3. Identification (confirming the isolated circuit corresponds exactly to the planned installation); 4. VAT (Vérification d'Absence de Tension using an approved detector tested immediately before and after); and 5. MALT/CC (Mise à la terre et en court-circuit, mandatory in LV when there is risk of induced voltage, backfeed, or bare overhead lines).

BR is a low-voltage symbol for short-duration, localized general interventions. For specified connection or disconnection in the presence of voltage, INRS states limits of 500 V AC or 750 V DC, 10 mm² copper or 16 mm² aluminium, and upstream protection of 63 A AC or 32 A DC, with the circuit off-load. Other BR work is normally de-energized and is classified by the exact task rather than a universal 63 A or 10 kW ceiling.

No. This is an English-language MCQ study adaptation, not an official translation or format simulation. The real process requires role-adapted theoretical and practical training and evaluation, followed by an employer-issued title. Ordinary training may be delivered by a competent internal or external trainer; it is not accurate to call every provider state-accredited.
