3KW mega flow water tank.

Is that what you've already got?
What rating is the fuse/MCB?
Does it supply an FCU which then goes to the heater?

At the moment it is not cabled.
Speaking with the plumbers they have asked for a supply to connect to the tank that draws 3kw.
Or is it better on 6mm cable run to a 32A mcb
They never asked for a fused connection unit.

why can't you use a 13A fcu? does the inductance on the element coil bring the overall impedance above 13A? is there a specific regulation that that stops the use of a fcu on a water heater circuit?
sorry if these are poor questions but i am still learning.

meant to ask will the total impedance (resistance + inductance) generate more than 13A in current?
i do know that impedance is measured in ohms, just wrote the question wrong.
If an inductive component increases impedance, will that increase or decrease the current flowing?

poor answer had a rethink.

obviously i am wrong. increase in inductive reactance will decrease in current.
as i said still learning.

elrobbo,
what is the unit measurement of impedance?
Do you think there is a significant inductance effect from the immersion element?
What you have seems to be acceptable subject to cable runs etc
It is important that you comply with the manufacturer's instructions. If in doubt then contact the manufacturer. I'm sure their technical number will be included in the instructions.

RMS
the measurement for impedance(Z) is ohms. stated this on above post.
the inductance will probably be negligible but as i said still learning, trying to improve and become a better spark. you don't get to the top without trying to improve. every one has to start some where i suppose.
