Rcds in series

[Silly Sausage]

Figuratively they are wrong then

They are in series because if one or the other trips, circuit is dead.

Are they ? ? ! !

I know what you mean, you know what you mean, but does Mr, miss Mrs Trainee or Mr, Miss, Mrs or Mr DIY know what you mean?

NO They Aint series is L or Pos to L or Pos as in series parallel circuits

Does it matter.

 

[davesparks]

Do you mean in Parallel? as RCDS require a N to work properly, or at all

I would say they are in series, not in parallel.
When connected in series all of the load current passes through each device, when in parallel the load current splits between the devices in proportion to their impedances.

From your link:
"Components connected in series are connected along a single conductive path, so the same current flows through all of the components"

With RCDs in series the same current flows through both devices (assuming nothing is branched off in between the). They are connected along a single conductive path, but having two poles they are each connected to two different parts of the same conductive path.

Might do to some westy, those with less experience than me or You, because we know what I meant doesn't mean everyone does, after all we do have to cater for all sorts, don't we?

Think of it as logic gates.
In series, both rcd’s have to be closed to get an output... A AND B = C
In parallel, either rcd closed would give an output... A OR B = C

It’s just no one would deliberately wire 2 rcd’s in parallel like that.

They are in line, not series.

They are in line, not series.

See @davesparks post #16.

They are in series, the L and N parts of the RCD are just in separate places along the circuit.
