    40. The shocking circuit connected to the patient includes a 1A fuse and a residual current circuit

    breaker (RCCB). The pulses of current only last for 1.5 milli seconds.

    Here are two statements about this.

    1 Residual current circuit breakers are designed to act more quickly then fuses but cannot

    completely present a shock.

    2 If the shocking current exceeded 1 A, the fuse might not blow because the current exists

    for such a short time.
