Installing (2002) Delta TS
In the owner's manual for my (new to me) Delta TS (36-841), it says:
"This circuit should not be less than #12 wire and should be protected with a 20 Amp time lag fuse." Not being aware of this detail until now, I was just going to use a regular 20-Amp circuit-breaker (I ran #12 wire). Please advise. Thank you! Bill |

Nope, he'll be fine (as he discovered in further research and posted) as circuit breaker as opposed to fast-acting fuse has enough inherent lag time for the motor... -- |

Old fuses would blow with the initial spike of current when saw motor kicked on. A modern circuit breaker needs to heat up to trip (except in the case of a short) so it can't get hot enough to trip from the very short current spike of the motor's start-up. At least that's my layman's explanation of it. :-) -- -MIKE- "Playing is not something I do at night, it's my function in life" --Elvin Jones (1927-2004) -- http://mikedrums.com ---remove "DOT" ^^^^ to reply |

My 3HP Unisaur has been on a 20A (240V) circuit, with 20-30' of 12-2 W/G between it and the panel for years, with zero trips. Come to think of it, it was ~50' in my last house. |

No, in addition to the thermal detector, circuit breakers have a magnetic trip. A high enough current will trip the circuit before the thermal detector can trip. |

Looks like you're on to something. - Sparks flying is a bad thing. - You can glue/solder pieces together, but it's not always a good idea. - You can never have too many clamps/outlets. - Measure twice, cut once applies to electricity too. (Measure, power good, cut off at breaker, measure again, no power, probably safe to work.) - You don't have to match colors to make things work, but not doing so is the sure sign of a clueless hack. (Intentional mismatching is ok.) - Hand planes and wire strippers remove the outer surface of the workpiece. - Copper turns green with age, so do trees. - Running the wood backwards through the saw won't reattach it... Not even if you swap the motor leads. - The sun can be used to generate wood or electricity. |

I=E/R, if you double the voltage you halve the current. Also, wattage would prove that out. The same motor wired 240, would draw half what it did on 120. On single phase, the neutral (white or ground) is the center-tap of the power transformer. That's why it's half the voltage. |

Don't matter whether you're running 120 or 240. Yes but a 240 V circuit has two 20 amp leads, a motor drawing 20 amps, 10 per leg.

I=E/R, if you double the voltage you halve the current. Also, wattage would prove that out. The same motor wired 240, would draw I get it. I'm also gently reminded/informed that a 240V circuit is Not the equivalent of two 120v circuits. Thanks, Bill half what it did on 120. On single phase, the neutral (white or ground) is the center-tap of the power transformer. That's why it's half the voltage. |

So, a 240v circuit apparently doesn't have a direction....or rather, it has 2 directions at the same time, from one leg to another, and vice-versa. Bill |

I'm also gently reminded/informed that a 240V circuit is Not the equivalent of two 120v circuits. It is, really, except that the two circuits are out of phase, so they add (if they were in-phase, they'd subtract). Thanks, Bill half what it did on 120. On single phase, the neutral (white or ground) is the center-tap of the power transformer. That's why it's half the voltage. Yes, on the pole, and the neutral is brought into the panel. However, there is no neutral in this (240V) circuit. It's not needed because the saw doesn't use 120V (if wired for 240V). |

Have at it, you're set to make sawdust ... no further need for bits and bytes. .... Unless he's using Austrailian electricity or has a Canadian saw/sideways breaker box!? Does the Australian electricity turn the other way? |
