hi all

wanna find out.
can a power port support a 220-240V fridge togther with a 220-240V cooking hood??
will overload?

thanks

look at the rated power consumption. for normal fridge and hood should be no problem. ceran-hob cannot - you would need individual plug with higher rating for that just like the oven.

Advise not to share. If you going to use multi plug to share.

Is not about voltage, is about Watt, aka power.

i think, the accurate way is to look at the current (ampere). If it is above 13A, your plug fuse will burn. If it is not burn, the DB fuse will switch off. If it doesn't switch off, the house will be on fire...

So, current (A) = power (Watt)/ voltage (240V).

Add up all current consumption from each appliance in order to see whether it is overloaded or not.


By the way, please don't take my word. I'm hoping someone can tell me whether what i'm saying is right or not..

13Amp usage will not burn the fuse, most fuse have some extra tolerance. Is not digital fused. MCB is usually 15Amps for socket. IT won't trip too.

First you need to check your load. If its not motor / compressor load just sum all up. Say your equipment A is 1000Watt, equipment B is 1000 Watt, Equipment C is 500 Watt. This only use 10.5Amps (using 240Volt). So is technically withing the limit.

But ideally in real life we don't connect to many high load equipments in once socket or don't stress to the limit. Because you don't know the condition of the socket, your quality of extension, and wires..

so in that sense, do u think a fridge can share the same point with a hood (not on 24/7) of course..
im jus afraid of overload tat is very dangerous

Check your hood and fridge power rating (Watt, or Kw)

3600Watt / 240V = 15 Amps, that is really the threshold. Do remember sometime voltage can drop to 230v, that increase the current.

And to really use 15Amps, you need the round socket.

All depends on what else is sharing the circuit from your DB. Cooking hood should not be a problem with the fridge as the power consumption of the hood is up to 300W (or 1.5A). Check your hood specs. Similarly a normal fridge should be fine. If in doubt check with a competent electrical contractor.

1) What Brand of your hood?
2) What the requirement of hood? 15A or 13A? (the sale should advise)

a side-by-side-doors fridge consume 0.7A - 1.3A+, a hood consume max 2A only....so there is no overload problem here whistling.gif

New standard by Suruhanjaya Tenaga - Single Phase electrical supply in Malaysia is rated at 230V +10% -6%

I = P / ( V * PF ) where PF is the Power Factor (0.85)

Generally, load the circuit to not more than 70% of the total rated carry amp considering the in rush current of your devices.
