faster and resettable

18
Q

what is an RCCB?

A

residual current circuit breaker

19
Q

what does the RCCB do?

A

breaks the circuit

20
Q

what are the advantages of an RCCB?

A

protects the user

21
Q

what is the ring main circuit?

A

the wiring that connects appliances together in parallel

22
Q

what are the advantages of using a ring circuit?

A

cables made thinner because there are two paths for the current
each part of the cable carries less current because it flows two ways
more convenient since sockets can be placed anywhere on the ring
individual operation of sockets
