Should I split PSU load?

[Rob99]

In my current smart home project I have a total load in the panel of around 30A. Should I just use one big PSU rated at 30A or split the load across say three 10A PSU's?

So if the PSU fails, it all fails?

30A? that's about 7kWH, that's about £1/hour, or £168/week. i would not call that a smart home, i'd call it a money spinner for supplier.

Yeah, that was my big concern too, hence I thought splitting it across a number of PSU's might be more sensible.

Sorry, didn't give you enough info - loads are all 24v and 30A (less than 800w) is the maximum assuming I switch every single light and LED strip on at the same time at maximum brightness.

 

[telectrix]

so you mean 30A @ 24V equating to 3A @ 240V?

 

[Rob99]

Yeah I guess that's how it works out

I’d be looking at building in some redundancy and backup if it was my house.

Also remember to include fuses or other protection for the wiring and strip. Splitting into 10a PSUs would also mean the overload protection on the PSUs would protect each circuit at 10a. I watched an interesting video recently about short circuit current and overload protection for LED strip. It's sonething people often forget.
