What fuse for IEC socket?

[PilouPilou]

Hi RIU!

I'd like to add to my DIY light an IEC socket that integrate a fuse, but I don't know what amperage I need to choose for the fuse... :/ so many choices!
I don't know if it is important but I'm on a 230V domestic electrical installation.

Thank you guys for your replies!

depends 100% on the amperage you are putting thru it and nothing else. all of those fuses are rated for 250V minimum

take your standard operating amperage and bump it as little as possible above that.

im gonna guess 3-5A if your fixture is 230V but thats just a stab in the dark without knowing the specs of your light

How much wattage do your lights have?
10 or 16A are usually used at 230v. A slow fuse should be sufficient, because a fast one could be already triggered by the inrush current.

Thx @CobKits and @Randomblame for your replies.. in fact I have 4 lights! I was sure (like a nooby!!) that there is one same rule for each light concerning the fuses I need to use!
A 4x CXB3590 that is connected to an HLG 240H-C1750B, 2 3X VERO29C that are connected each on an HLG 320H-C1400B and a 2x VERO29C on a HLG-C1400B

So roughly 1200w at the wall.
If they all are connected to the same IEC socket use a slow 16A fuse. Inrush current of an HLG-320 is ~70A, a too small fuse or a fast one could be already triggered when the light is switching on.

Hi! no each light will have his own IEC socket. The lights are in different grow box.

Ahh, okay! Than take the slow 10A ones.

Thank you very much for your help.. you rock!

just take the current draw as printed on the drivers at 230 and multiply by 1.5 for a starting point. as RB said you might need slow blow fuses. you'll prob end up at 3,4,5, or 7A

I am checking the website where I want to buy the iec socket and the fuse:

For the socket 10A is it good?
For the fuse 10A too but I don't see slow fuse, I just have the choice between temporized and semi delayed, there is fast and super fast but you told me to don't choose that.

15a average 20a max the amount of a normal branch circuit.

Hi! 15A for the fuse? 10A for the socket is enough?

 

[CobKits]

i would call 10A 'light duty' and 20-30A 'heavy duty/commercial'

heck a plug in domestic wall electric heater/hair dryer/toaster/coffeemaker all pull more than 10A. which is why most wall sockets are rated for 15A minimum and NEC requires multiple 20A small appliance circuits in new construction

the fuse should not be higher than the rating of the socket itself

a 15A fuse is completely redundant if the circuit breaker that feeds it is also 15A

fuses/circuit breakers are most commonly rated to protect the wiring between the breaker and the recepticle

some general rules of thumb
10GA wire requires a 30A breaker
12GA = 20A
14GA = 15A

With a fuse inside, I don't find an IEC socket that is rated more than 10A on the website I'm checking.

 

[CobKits]

possible

most iec power cords are 16GA anyway

if you think of the fixtures that use them they are not power hogs

13 amp fuse is UK standard for IEC cords with 3 x 1.0mm2 Cable.
5 amp fuse for cable with 3 x 0.75mm2 cable.

If you are in the UK all plugs come already fused so there would be no need, but you might be in the EU so since the VAC is similar I cant see there being much difference.

Try another website or get them from e3ay, mate.

5a on the 185 driver.
13a on the 320 driver.

10a for an outlet normal. like cobbkits said
