Many people say that you can’t put certain appliances on a GFCI ie: Washing machine, refrigerator, sump pump etc… I’m wiring a corded submersible sump pump in a damp 1/2 basement, by code GFI’s are required in this type of basement.
So if you can’t put a sump pump on GFI due to excessive tripping from motor start ups, how do you comply with code and yet maintain a safe connection if you do not use a GFI? This pump also has a dedicated circuit with 20-amp line.

Jeff - Did you get to all the posts under your previous question? The code section was fully quoted by RickG, including:
i Exception No. 2: A single receptacle or a duplex receptacle for two appliances located within dedicated space for each appliance that, in normal use, is not easily moved from one place to another, and that is cord-and plug-connected in accordance with Section 400-7(a)(6),(a)(7), or (a)(8).
Don't forget your battery backup pump!
b Been there, done that, pumped it out
*Use a single outlet receptacle instead of a duplex receptacle and keep the pump plugged in all the time. That's what the above code quote states.Frank
*Thanks for the replys Jeff and Frank,Your thoughts on wiring additional receptacle outlets for woodworking equipment such as a mobile table saw, radial arm saw, etc... hand held power tools, convenience needs, to be used in this same space, "currently damp", unfinished half basement? Since only one tool, machine or need item will be used at a time, would an additional 20amp dedicated run GFCI with downstream outlets off the load side be sufficient or would a GFCI breaker with standard receptacles be a better alternative(I would like to install about 3 or 4 outlets at various locations in that space for the above uses). Or would the machines also trip the GFI?Standing on a sometimes damp concrete floor working with metal machinery and power tools seems risky without GFCI protection.
*Jeff - You won't like my answer which is that IMO woodworking and dampness don't go together for many practical reasons in addition to the safety reasons that you mention.Jeffb Been there, done that, can't remember
*First get rid of the moisture. If it just humid then a dehumidifier should do the trick, plumb its drain to the sump pump. High humidity means your wood will be larger while working it and shrink after you carry it to its destination. And probably other things I am not aware of...Maybe a good discussion for Knots?If any tools run on 240 volts, use dedicated single outlets and no GFCI. But, make sure the case, frame, etc. is grounded for your protection. You may want to run a separate ground wire and not rely on the cord & plug. This only applies to stationary tools.For 120 volts, use can use a GFCI and also use the outlets for portabe tools. If the GFCI trips, you will be standing right there to reset it. While it may be bothersome, it is not like a refrigerator or sump pump that if the GFCI trips, much damage can be done before you discover the power is off.Frank
*Those power tools generally won't trip a GFI. Most temporary construction power is GFI protected and all kinds of tools are used, usually no problem. You can, if you want to fork out the bucks, get a 2-pole GFI breaker for a 240v table saw. Lee
