I recently got a CT15 as my first Festool vac. I am happy with it. Uses are with ETS 125 REQ, track saw, and biscuit joiner, pocket hole jig, other small tools. I didn’t need Bluetooth, wheel brake, or manual filter clean. I did order the MIDI hose garage which is compatible, but have not received yet. That’s really my only complaint - the cord and hose storage on the CT15 leaves a bit to be desired out of the box. I will second that I love how light weight the CT15 hose is. I’ve never been zapped by a vacuum so not worried about antistatic at this point. Tool activation and variable suction are awesome.

I suggest make sure you know the differences the MIDI gains you, and if they matter to you. If price is important (it was for me), in my opinion the CT15 is a great value.

I'm leaning more into the CT15 now that I Know I can just get the AS hose in the future. I don't care about the other features like you said.

I agree the AS hose is ridiculously expensive, but the smooth exterior instead of the typical ribs is very nice when sanding a finished work piece, or even when sawing where it doesn’t tend to catch as much on the track.

Most likely not a coincidence, you’re being tracked.

I haven't seen this mentioned: the first 1100mm (or so) section of the CT15 hose is slimmer than the rest; approx 36mm vs 41mm in OD. That makes the hose lighter as well as more easy to bend or handle.

If I still had the TS75 to use with this extractor, I'd definitely go with a hose sleeve to attach the power cord to the outside of the hose. something like this: https://www.hosewraps.com/

Re: Festool CT15 - Amp

I got a clamp meter from Amazon, and measured the current draw on the CT15:

Lowest setting: 4.68
Max setting: 8.24
Start: 12.83

I'll do the same on the DF500 used with the CT15, & then the Kapex EB alone. So far the starting and use of the CT15 and DF500 plus two lights (0.34amp in total) on the same circuit hasn't tripped the 15amp breaker. Perhaps the DF500 draws 1 to 2 amp only?

Amp breakers are about sustained use, for a start they can take 5x or 10x times the current depending on the breaker type.

Ref breakers you need to worry only about the averaged (over 5+ seconds or so) power use, not the momentary max values.

An electricity dummy here. ;D

No wonder why the saw didn't trip the breaker until the board was fed for a little while

Momentary max is only relevant for the magnetic trip. It's probably similar in the US, but in NL we have the B characteristic as most common; tripping instantly when current is >3-5 times the nominal rating, C-char. for >5-10.

If you go below that, you have to wait for the circuit breaker's thermal trip device to heat up. This is depended on the ambient temperature, available cooling, etc. Double the rated current can take something in between 10 and 50 seconds. 1.5x nominal current... 40 to 400 seconds.

You might even get away with hours + at 140%

I went digging for it before when breakers came up, but yes, we have a similar trip curve to what you describe. A little bit over will go basically indefinitely. I've measured circuits before that would run over 16 amps basically endlessly (things running a microwave or similar).

Hard to find one for typical breaker, but looks like they can do 2X current for about 8-25secs,  1.5X for up to 90s, and 1.25x for basically forever.   So 15A circuit could do 18.8A basically forever, an OF2200 takes 18.3A peak.  So thus why folks aren't kicking breakers.  Wire house with 20A circuits, and no problems at all.

Typical Breaker   I found this one, which is a common breaker here. It's an old curve, I'm not sure if things have changed since 1980, there might be higher temp requirements now, which would shift times down.

They all work to the same curve here. I wouldn't be surprised if the breakers in Europe use the same or very similar curve.

I'm adding two 20amp outlets to my shop.

Festool Kapex EB Alone

Start: 15 - 16 amp; Running 8.5 amp or so.

Given the motor history for the EB model, the Kapex and shop vac/dust deputy are connected to two separate 15A circuits via an auto-start switch.

If you unplug the CT15 while it's running and then plug it back in is it still running?
If so, that would work.
If not, the nit would not.

I was completely convinced that I was going to buy the Ct15 when I got my DF500.
But I really wanted to add the hose garage so I could stack systainers on top of it.
And I kind of did want the better hose.
Ultimately I ended up getting a MIDI I.

You made the right choice as the features you need/want aren't included in the CT15, or will come at quite an additional cost.
