Electrical qualification: according to NF C18-510

The electrical qualification title issued by the employer includes a symbolic coding made up of letters and numbers. Through this electrical qualification, the employer authorizes their employee to act within the framework of the qualification granted and after appropriate training.

1- Electrical qualification symbols

1-1- The first capital letter indicates the voltage range of the installations on which the holder is authorized to work

of the electrical authorization can work or intervene on:

B (low and very low voltage),
H (high voltage).

1-2- The second character (number or letter) specifies the type of operations the holder can perform :

0 (non-electrical tasks),
1 (performer of electrical tasks),
2 (in charge of electrical work),
R (in charge of general interventions),
C (in charge of isolation operations),
S (in charge of basic interventions),
P (operations on photovoltaic installations),
E (in charge of specific operations: maneuvering, testing, measuring, verification).

1-3- The third character (a letter) is optional and specifies the type of operations that can be performed:

V (work in the vicinity),
N (live cleaning),
T (live working),
X (special operations defined by a safety instruction).

1-4- Finally, an attribute that completes the previous characters if necessary:

Clear writing of the type of operation, verification, testing, measurement, or maneuver by an operator.

OPERATIONS/TASKS	AUTHORIZATION2011	NEW AUTHORIZATION 2012	OBSERVATIONS
Non-electrical work in low-voltage electrical environments	B0	B0	Applies to executing personnel and site managers
Non-electrical work	B0V	No longer exists	To be redirected to: – B0 if non-electrical work – BS if replacement and connection intervention (socket, light fixture…) – BE maneuver if allowed maneuver operations
Non-electrical work high voltage	H0-H0V	H0-H0V	The field applies to executors and site managers
Routine operation of low-voltage installations: resetting protection, maneuvers, changing fuses	B0 or B1V authorized or limited to:	BE – maneuver- BS	The trainee must have a technical prerequisite to access the training
Replacement and simple connection operations: replacing bulbs, replacing switches, sockets. Connecting equipment to a waiting circuit (boiler, roller shutter…)	B1V limited to or BR limited to:	BS	The trainee must have a technical prerequisite to access the training
Low voltage electrical work	B1-B1V/B2-B2V/BC	B1-B1V/B2-B2V/B2V TEST BC	The field is restricted to tests within the framework of the work.
Low and high voltage electrical work	B1-B1V/B2-B2V/BC	B1/B1V/B2-B2V/B2V TEST BC	The field is restricted to tests within the framework of the work.
Maintenance and troubleshooting interventions for low voltage installations	BR	BR	BR is redefined and is only included in maintenance and troubleshooting interventions. Measuring, verification operations… are included in other symbols (BE, HE…)
Specific measurement operations: testing on test platforms, regulatory or functional checks	BR-H1V	BE MEASUREMENT/ BE TEST/ BE VERIFICATION/ HE MEASUREMENT/ HE TEST / HE VERIFICATION	New symbols: specific operations
