Has anyone wired multiple accessories to one can smart circuit? My dealer was saying that they have done it. It would mainly make it like a power port without cutting into the bike's wiring harness I assume.

I'm wanting to do this with possibly the radar detector, camera maybe a phone charger all in one circuit. I would have to assume they together do not pull many amps.

Any thoughts on this? I would have the cansmart set to Accessory as I would only need key on power.

Thanks

I've done this with a phone charger, top case usb socket, a switched live for my Dashcam and also as a +12v trigger for the Amplink. Just need to make sure you don't exceed the current rating of the Cansmart circuit.

@Gixxerific , that would work fine with the eZCan. I've done the same thing but using a PDM60 as the power source. But, you should add separate, inline fuses with each of the components before tying them all together. Otherwise, if there's a short you could fry everything before the eZCan circuit trips.

What @Gunnert said is correct. Putting more than one load on a circuit simply means you must sum the total current draw consumed by all loads and set that value (plus a little more) as your clamping value. And, as he said, it is always good to protect each device - cheap insurance.

Thanks all I just needed a second opinion.

@KAS_UK good to hear I will be pulling roughly the same load you did/are I will do the math on it all before the final wiring.

Thanks, @Gunnert I hear you on the inline fuses. Thankfully most if not all what I'm wanting to use already have stock inline fuses. Bonus!!! 🍻

Ok, it's 23F degrees out, time to take all my body work off again so I can wire loom and tighten everything up. Had to put it back together so I could ride the other day.

Absolutely. Add up the current draw of each device, and make sure it's well within the boundaries of the circuit's configured amperage. I'd say don't exceed 70-80% for the headroom. There's probably an official recommendation out there.

One thing to be aware of when running multiple individually fused accessories from one EzCan circuit is that wire type fuses will tolerate a surge current considerably higher than their rating, while the “electronic fuse” on the EzCan will “blow” even if there is a momentary small over current draw.

This means that it can still be possible to trip the EzCan current overload before a physical fuse blows if there’s a short on one of the accessories.

This isn’t necessarily an issue, but unless it’s understood it can make it difficult to diagnose a fault.

With the ezcan you allow for the surge amperage by making that circuits fuse amp rating higher. Each circuit can be set for a range of amperages. You pick one.

For example, if your standing load is 4 amps but you have surge load of 7 amps you would set that circuit to 7.5 amps.

All the input above is correct. If you are looking to run your RD that is .5A, your phone charger that is 2.5A and another dongle that is 2A, you'll have to configure the EZCan circuit for at least 5A if they will all be running at once. Having a little buffer is a good idea BUT don't go up so high that you smoke the circuit before the internal 'fusing" trips.

That's a possibility, but only if the rest of the wiring is up to a steady state 7.5 amp current draw.

The real issue could be solved if there were a much more elegant solution involving an override setting for "maximum surge current" and also "maximum surge time". For example a circuit wired for 4 amps steady current could remain properly protected in that example if there were parameters in addition to the basic "maximum current" set to 4 amps that allowed (say) max surge current = 7 amps / max surge time = 100 milliseconds.

I am not really following you.

Your home electrical panel has a bunch of breakers. By code you install a breaker that allows surge of 25%. For example, your dryer is on a 40 amp circuit. The dryer is rated at 32 amps to give that surge protection on startup.

I don't see a reason to have anything more complicated than what the ezcan already gives us. Hex allows us to set the amp max for each of the 4 circuits. If your riding lights are 10 amp then set that circuit for 15 amps. The wiring size is not an issue at those low levels. The ezcan I think has 18 gauge wires which is more than enough for the small amp loads that goes through any circuit. With the ezcan it is the internal circuit board that is the limiting factor and not the external wire size.

Am I missing something?

You can indeed run heavier cable than would otherwise be required if you wish, and in many respects it’s the simplest solution. The big advantage of tight overload regulation is that you can use lighter (smaller) cabling.

BMW take advantage of that as evidenced by how light gauge the standard loom cabling is, but I accept that isn’t normally a great issue for motorcycle accessories other than when you have limited space to run heavier cabling.
