ToolBoard 1LC fuse rating
-
Hi,
Looking at the documentation for the toolboard it suggests putting and inline fuse which I would like to do, but do not know how to calc the required amperage.
50w heater, 17HS10-0704S stepper with rated current/phase 0.7a
Using this site https://www.electricalsafetyfirst.org.uk/watts-to-amps-calculator/
I put 51w in to take account of the stepper and heater which then calculated 2.13aThe smallest Blade fuse based on the above is 3amps.
Is this safe or do I need to look at another solution, please.Regards

Hi,
A 3 amp fuse should be fine but what voltage are you using for your calculations?

Well the heater alone is going to need 2.08 amps. Add the current for the stepper and you could be up to 2.64 so a 3 amp fuse seems good - if it blows try the next size up.

The tool distribution board uses 5A fuses.

@oliof Morning, I was about to say, I do not have a tool distro board, but then saw the relevance of your reply!
I have a selection anyway, but thanks for the info, good shout.
I will start with a 3 and see what happens.Regards,
Paul
