3.8 Performing an RCD test on an installation RCD

When performing an RCD test ensure that

the Continuity Test probe is disconnected

from the PrimeTest 250

Equipment which is connected downstream

of the RCD may cause measurement

inaccuracies.

Voltages between the protective conductor

and earth may inﬂ uence measurements.

Leakage currents in the circuit may

inﬂ uence measurements.

Potential ﬁ elds of other earthing

installations may inﬂ uence the

measurement.

The PrimeTest 250

can be used to measure the

operating time of an installation RCD.

Connect the PrimeTest 250

IEC lead to the IEC

socket of the PrimeTest 250

and a mains outlet on

the RCD protected circuit.

To test the RCD operating time press the 30mA

RCD test key.

The mains supply status is checked and the status

is indicated using the LN, LE and NE enunciators

of the LCD.
