TSC-10HB - What's all the fuss. :)
Got my TS delivered this arvo and spent the next 2 hours setting it up. Many thanks to Dazzler for his posting on assembling it http://www.woodworkforums.ubeaut.com...light=tsc-10hb
From thread: MJ-2325B Table saw.

Lucky beggar, Brisbane has run out, mine is on a slow boat from China or Taiwan
and wont arrive till around 14 August.

Seriously, I can't see it being an issue at all. My Festool DC combined with the saw or router dims the lights more than this TS. I'm going to sleep well tonight.

Thanks David. So then, only 25 more sleeps.
Plus a few more till I can get to Brisbane to pick it up. But ive been hanging out for one for about 2 years but something always gets in the way so a few extra days wont matter :eek

It seems to draw less power than the 2HP rated MJ-2325B - go figure.
Start up current will be higher than running current due to the motor overcoming the inertia of the rotor to accelerate it up to its running speed. Once at this speed, the only current draw will be the load imposed by mechanical friction and air resistance of the blade and the internal losses of the motor (a bit vague on this last point!)
So , your 3 HP (?) motor won't be developing 3 HP until you load it up with a substantial cut. Then you will see the amps rise.
One other point of interest 1 HP = 0.746 kw, therefore, 3HP = 2.24 kw. Assuming this is single phase, amperage = Power/Voltage so the nominal current would be 9.3 amps (assuming 240v).
Any sparkies out there, feel free to contradict me if I am completely wrong.

The fact that the lights dimm (as at my place) means that the power circuit is having trouble supplying the current requiments of the saw. If all is well with the power circuit then there should be no dimming of the lights. From a previous post on this start up current of my TSC10HB is about 40 amps.
Most older houses only have 6mm cable from the supply to distro board. Newer houses have 16mm cable. This combined with long power runs to a shed can realy give some trouble.Specializing in O positive timber stains

6mm square is what I have :-(
Hi Alex,
6mm square supply is all there is to my place (63 Jennings built place with Gas hot water and heating). 16mm square would be nice.
Following up on the question "why doesn't the circuit breaker trip" ... They are designed not to. Really big currents will trip them nearly instantly via a magnetic mechanism. Slightly over the 16Amp rating of a standard power circuit ie 17 Amps, might take several hours to trip the breaker and it is via a thermal mechanism.
The 40 Amps drawn by the induction motor is small enough to not trip the magnetic mechanism and does not last long enough to trip the thermal mechanism. There are special circuit breakers with higher magnetic setting just for use with induction motors.
For more than you want to know see the Clipsal brochure
http://alfred.clipsal.com/scripts/ap...rochure&ID=595
page 4 of the brochure (acroread says page 5/62) has a nice diagram showing the construction internally.
page 6 (7/62 in acroread) has a curve showing the time to trip on the y axis verses the ratio of current drawn to the rated current of the circuit breaker ie 1 is when 16 Amps flows through a 16 Amp circuit breaker. thus for 40 amps through a 16 amp CB, the current ratio is 2.5, from the curve that will take 10-40 seconds to trip ... by then the motor is well an truly running (we hope)

Correct Link .. sorry
The link to Clipsal info is

It is 1.8MB
Sorry
