I did read somewhere that using AC coupled inverters with PV does create a lot of system losses due to the number changes of DC to AC...

Apparently from what I read is that batteries can be added to any grid connect inverter using AC Coupling, meaning you don't have to...

As mentioned above a clue can be whether a it’s an instant loud trip (magnetic mechanism) or takes a bit longer (thermal trip) If you...

erm... NO....? As IR tests between all live conductors are normally only required on cables/circuits during new installations, rewires...

sounds like a big enough place that no matter what you generate, it will be used. so rather than focusing only on the pumps & trying to...

And if it goes instantly with a loud bang, rather than after a number of seconds, you can assume its kicking out on the mag, for a B32...

If you have the probe with test button, not too bad. But I know what you mean. Megger has had hands free continuity tests going back to...

The chemicals are checked in the morning and afternoon for CL, PH, ALK, and Hardness, but the pool remains fairly constant with a few...

Is the pool open 24/7 then ? As this one, the pump is shut off overnight.

The way they went with the holiday complex pool heating was to use solar tube instead of electric.

Hence, why I said maybe :) It certainly looks cheaper.

This one maybe cheaper. https://suvastika.com/the-mcb-testing-machine-a-valuable-tool-for-su-vastika/

Admittedly but this was basically a real life situation let to run with a real loose connection fault creating a real arc that could...

I tried a Hager AFDD on both radial and ring final with various currents connected via a socket outlet. My conclusion was that they...

That EICR is at best very poor with a lot of information missing and / or lost in the incredibly poor formatting within the NAPIT...
