Cylinder 4kw

[NoNonsense1000]

Was looking for some advise. Plumber has installed water tank with three 4kw elements at the moment I have ran three individual circuits. At the moment the salon is running of the boiler. I am just looking if anyone would know what 7 day time clock would be suitable for 4kw. Want the contractor idea as last resort. Can anyone help?

Sangamo timeswitches are rated to 20Amps, but obviously you will need 3 seperate timeswitches which are running at exactly the same times for 3 seperate elements which is a bad design.

You would be much better off using a single timeswitch to pull in some contactors to switch the load.

As Dave says, a single timeclock and contactors is the logical way.

If they're currently running on a boiler, why do they want to change to electricity?

Thanks. Can u give more detail? Does that mean doing away with 2 circuits I have ran. Using one on a single time clock then to three contactors then to the three elements?

It is for a salon and the demand needed isn't enough.

I think he means this device with 3 elements is the boiler

 

[NoNonsense1000]

The boiler is just for heating. And back up if needed.

Just read it again and you might be right!

Was just making sure. In that case can a standard single 16 amp time clock be used instead of the 20amp sangamo?
