Lighting spur off a fuse spur

[Mr. Anderson]

Maybe I did know it but it's gone now, so please refresh my memory.

You need an dedicated radial to the shed!

oops, sorry, I meant your customer needs a new radial.

Cheers, I will remember that. Now are you able to tell me how to work out the kW from kWh?

time to get my coat......

kWh = Power (in kilowatts) x time (in hours)

You do the rest...

i dont think it really matters now , do you ?

customer wants lots of appliances in shed = 32A dedicated radial wired in 4mm swa.
why bother with some pointless calculations.

If you tried to google the manufacturers data you will see that the dryer alone is 10A

may i direct your attention to post #23.................

Just showing the OP that the information is easily available.

You were just guessing

yeah , but what a great guess.

Now that rings a bell, thanks! So (and this is from memory so I may very well not be getting this right) if E=Pxt then because I've already got the watts per hour then the math for the tumble dryer is...
E=Pxt
1.4kWh=1400x1

A=w/v
5.8A=1400/240

So then a 6A fuse should take that load. Obviously I have other loads to add to that in this situation BUT from what you guys are saying that seems very low? And now I've just seen the manafactorys details which prove my math to be wrong. Bugger this, I give in and will now just google the details.

Lol. Ok I'll hold my hands up there and say I'm a thoughtless ---! Thanks for the tip.

I'm doubting my math now. To work out the amps when all I've got is the annual consumption I take the annual and divide by 365 (days) then by 24 (hours). This then gives me my watts per hour, I can then add up each appliance and divide by voltage to give me my total amps to find my breaker size?

what are you drinking tonight?

230 is the voltage used in calculations.

absinth with tequila chasers ?
lol.

In them situations just go to manufacturers website 1 min and bam 10amp for dryer rest will be just as easy to find.
