fault loop impedance

what do you bridge together to measure fault loop impedance

• A-N

• A-E

• E-N

what things affect impedance

• length

• CSA

• material

• heat

what tables cover fault loop impedance in the as3000

• T8.6

• T8.1

• T8.5

• T8.2

under normal conditions does current flow in a neutral conductor

what makes up impedance

• resistance

• capacitance

• inductance

• reactance

do you test for impedance on a live circuit?

under what conditions will current flow in a earth conductor

what type circuit breaker is typically used in domestic installations

• a

• b

• c

• d

at what point (Eg. which socket outlet) would you carry out an earth fault loop impedance test

are you feeling confident

• yes

• no
