Cable Size for Generator 100KVA

[Eduardo Maun]

I have existing generator with a capacity of 90KVA the cable size I used is 4x95 mm2, I decided to change 90 to 100 KVA, Can I still use the existing cable or should I upgrade the cable size?

Thank you...

May God Bless us all

best regards,
Eduardo

You don't need to upgrade the cable as long as the lenght does not exceed 600 feet

Method of installation? What is this?

Free air, clipped to wall, on cable tray, buried etc. Used to derate for heat buildup.

Is this four single 95mm SWR cables or a four core SWR cable?

 

[izak]

you forgot laid out on the ground as single twisted strands of bailing wire with brown paper bags wrapped around it

 

[dbuckley]

I hate those sorts of jobs. There are brown paper bags and brown paper bags, and sometimes the derate tables are all wrong...

Your cable or conductor size has to be compatible with this 200A
