RCD ZS

[Chr!s]

What the maximum ZS for a circuit supplied via a 300 mA RCD, any ideas

Cheers

Is this an exam question?

Wouldn't we need to know the overcurrent protection device and earthing arrangement?

230v / 0.3a = 766.67ohmz.

you need to use touch voltage of 50v. not 230v

Dont you take the max Zs value from the next device back in the circuit?
