Heaters,

[Julius]

Hi everyone
Just a quick question, there is 2 × heaters at 1200w each, will a 2.5mm radial cable be ok feeding them on a 20A breaker,
Cheers

Have you worked out the load in amps per heater?

No

No

maybe a good place to start … sometimes the basics are seem to be boring but they do rather matter.

True

Yes it will be fine.

 

[SPECIAL LOCATION]

Power = Volts x Current so Current = Power / Volts

1200watts / 230volts = 5.22Amps per heater..

OR

looking at it another way..
20A MCB can supply 20A x 230V = 4600Watts..

Your two heaters are a combined load of 2400Watts..

So have have around 2200Watts of spare capacity to play with!
