Okay so i had it the other way around... i had the black in Neutral and then the red (the furthest one on the right) to the top of the astut and then the red (with the white wire) to the bottom of the astute.

Apologies for the late reply...just got back home and fitted it...and yep. Working brilliantly.
Thank you for helping out.

i have the same one for my geyser ..works nicely
however my wifi range isnt the best
i wanted to fit one for my pool
is your wifi strong by the pool pump or you did something else ?

You are using a 10A (inductive load limit per datasheet) switch on a pool pump (which can spike 6x power on startup)?

Pool pump is a .75kw - i figured if it can work for my geyser it'll work for my pump...You are using a 10A (inductive load limit per datasheet) switch on a pool pump (which can spike 6x power on startup)?

Yeah - well i fitted 2 repeaters as my entertainment area had no coverage... this resolved my isse with wifi in the yard as well.

Running current is not the issue. Pumps/Motors can potentially spike up to 6 times their rated power on startup. So the issue is that, that 750w become up to 4500w for a split second every time you turn on the pump.
Anyways, for now it might work but I am not sure if your insurance will cover you if something catastrophic happen because of the installation.

manufacturer rated specifically for pool pumps ,heat pumps and air conditioning systems .we install probably 50 per month ,never had an issue yet .it can handle a continuous load of 10 amp ,spike is probably 20 amp .You are using a 10A (inductive load limit per datasheet) switch on a pool pump (which can spike 6x power on startup)?

those wifi timers are 30a if not mistaken

they are also rated for connection to a standard 16 amp wall socket so that gives you 20 amp for compliance , current will be at least 100% for 24 hours,so ja probably safe for a 20 amp startup .i wouldnt drive a compressor off it though .

Cbi astute is 30a for resistive loads and 10a for inductive load. Look in the dataaheet on the cbi website.
Is the reduced rated amperage on the inductive load not specifically to account for the startup spike? i.e. it can handle a running load of 10a specifically because it can handle a startup spike? So a pool pump of 0.75kw is 3-4 amps running load, which is within the 10a spec.
Not 100% sure, and I don't use these for pool pumps so no skin in the game, but logically it would make sense. Otherwise, what would the rationale be for having a reduced spec for inductive vs resistive if the spec hasn't already accounted for the startup spike?
