Motor Max Fuse Size Tables?
Motor Max Fuse Size Tables?
(OP)
Just some info Req:
Does any have or know where I can get a table that shows the max fuse sizes (Time Delay) that can be used by code (CSA if possible) for a particular motor (@ a specific Voltage based on its FLA)
I could make one, for example at 600V (575V motors)
Motor FLA Max Time Delay Fuse
10HP 11A 15A
50HP 52A 80A

I'd contact Bussman and Shawmut, I'm sure they will be happy to help if it might sell a few fuses.

Thanks guys, slide rule is an awesome idea. I'll have to ask for one!
I started making an excel spread sheet. So far it is just for single motor branches: HP, FLA, TD Fuse and Cable size... man what a time saver then grabing the calculator and flipping through the tables.

Just a note: It is Table A24, of the old Consulting Application Catalog (pg A-58, Jan 1999)
htt
And Table 1.5-2 of the recent catalog (pg 1.5-7 June 2006)

In the 1998 edition of the CEC it was moved to table D12.
(Appendix D Tabulated General Information)
In the 2006 edition of the CEC it is Table D16.
See also Table 29 in either edition of the CEC for percentages.
Please note: The NEC refers motor horsepower to a table which gives the motor current to be used based on motor horsepower rather than nameplate ratings.
The CEC uses nameplate current.
respectfully
