2Kw And 3Kw Electric Heaters

[r.b]

I am just in need of info on this I know you can install a 2.5 on a 16 amp breaker or rcbo to these to a sw fused spur It would have to be on a 13 amp fuse in the spur and a 2.5 flex coming out of it wouldnt it?.3000 divide 230 =13amp and 2000 divide 230 = 8amp?Is this right?

Under WHAT conditions CAN you install a 2.5 on a 16a OCPD?

Why 2.5 flex?

Just asking

Thread moved as presumably this is a student question?

why 2.5 flex well nothing wrong with 1.5 flex still protected by a 13 amp fuse in the spur

 

[kerching]

So why 2.5 then.....just curious

 

[r.b]

Orite then kerching end of the day its protected by a 13 amp fuse both flexes can take the load in the real world you would use 1.5 flex probly cheaper!

should be fine putting 2 or 3kw heater on a ring circuit I think because rings take more amps if I put a 13amp fuse in sw spur surely it will be ok what are your thoughts?

Quit while you are alive bud :red card ray :shakehead

Not if its an immersion heater.

I think you need to quit electrical work before you kill some innocent person through your incompetence

and 7671 recommeneds loads over 2kw be on their own circuit...

Mmm to be honest they do sell, and I have bought one of them 3kw heaters and guess what it has a plug on it, so it can be plugged in to a socket, may be a raidal or ring. So if it don't have a plug, do as the regs say

if you are going down this line, would use 2.5 flex due to heater being on for long periods of time - helps stops cable overheating. I do get amused by kettle flexes these days, look like 0.5mm with 3kW element, but then they are only ON for a few minutes.

1.5mm cable over a short distance like this can carry 16A indefinitely

1.5mm flex can carry almost 40A over 20m if you see some of the garage installs I go to find faults on.

Correction...

You are just in need of 'Training' not 'Info'

the only thing you appear to know is how to search the internet   :coat   headbang
