Well im going to install a few shelly 4pm devices. But as it has 1 neutral input and 4 outputs im unable to output to 4 RCD's
Would i be best just installing a larger RCD (40A) to feed it then loop out to 4 x CB's for each circuit. However if i do have a nucience trip its going to take out 4 circuits.
Just brain storming really before i commit
Im a lecky by trade but do no domestic work. Plus when asking a contractor mate he was confused by what I want to do.
Why bother with a power saving device. I've been told electricians just run wiring around the metre at their own house.
Yea that's plan b, but I'd prolly loose my license.
It's easy to steal power hard to do it without being caught.
I just want to monitor and control my circuits.
I already do some devices such as AC and hotwater via Shelly so I can turn on 30min from home. As well as turn hot water off and on as I'm often on shift for 10 days.
4pm
Oh, its nothing to do with the time of day. It is actually power monitoring on 4 circuits.
correct its approved for use in Australia. Just a bugger to install as all power will need to go through this device to monitor it so it cant even be used to run some 220V relays
Why can't you output to 4 separate RCDs?
That neutral input is just there for the device, isn't it? All current measurements are taken from the active lines
just get a neutral link so you can get 4 neutrals. RCD's will work fine as long as the current entering the loop of each circuit is the same as the current leaving.
Yea looks like the wiring is horrible. But looks like it's not 1 in 4 out but. 4 seperate pairs of terms.
him it's a bit off topic, but do you know what is the difference between the Shelly 4PM and Shelly 3EM? 3EM seems to be dearer
Are you installing this yourself?
