Lighting spur off a fuse spur

[Guest55]

if the total current consumption of the appliances in the shed exceeds 13A , then the shed will need its own circuit of 20A or greater.
in other words , youll get away with a fridge and freezer , but wash mach & tumble drier use alot more power.

 

[Mr. Anderson]

Thanks Biff, I do understand that but I guess what I'm now asking is how do you work out the total load when the information you've got for each appliance is measured in kWh?

 

[Guest55]

the data stamped on the back of each appliance will be kW , not kWh's.
for example , a 2kw heater.......

2000w divide by 230v = 8.7 A

[Mr. Anderson]

I know that it will be on the appliance BUT they don't have the appliance yet all they're able to do it point at it on line and the only power information on line is in kWh. So how do I work out the total load with that information.

e.g.
Buy BEKO LX5053S Undercounter Fridge - Silver | Free Delivery | Currys
+
Buy BEKO WM74155LS Washing Machine - Silver | Free Delivery | Currys
+
Buy BOSCH EcoLogixx 7 WTW86561GB Condenser Tumble Dryer - White | Free Delivery | Currys

Presumably you would transpose the calculation to work out kWh to get the power and then do the calculation for current as usual.

I know how to work out a total load when given the appliance amps and that this info is on each appliance. I thought I had already explained this. I'm confussed about the "annual consumstion" and "kWh" part.

 

[Guest55]

i dont need to convert from kwh to kw to tell you that all those appliances are going to well exceed 13A lol.
tumble drier alone is nearly 10amps.
washing machine the same , and around 5-6A for fridge.

 

[Guest55]

with diversity youre still gonna need a 20a supply to the shed , which you cant spur off the ring for.

 

[ian.settle1]

Oh great a washing machine and tumble dryer.

Both on at the same time with washer on a 90 deg wash a bit greater than 13 A I think.

Sure you know what your doing?

 

[pencilpusher]

Adding a 13 amp supply will cause nothing but grief.

 

[Mr. Anderson]

Thanks Biff. Then to someone else, how do you convert kWh into kW so I can have a real understanding of whats required not an educated guess.



I'm not sure why I'm getting such a bashing here. This isn't anything that was covered in 2391 and I'm keen to learn how to do this.

 

[Mr. Anderson]

Yep, I see a 13a fcu is no good but can someone explain how I find out what is required from the information I've been given. Please remember I've not got the appliance to hand and only have info in kWh.

No! it wouldn't but you should know this from earlier qualifications you should have or not if you are asking them, are you a Electrical Trainee by any chance?

You need an dedicated radial to the shed!

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