Got some time off so busy setting up design templates for my common inveter, just so I don't miss anything silly and have a checklist of sorts.

Anyway this got me to thinking of ambient tempreture correction...

What would the temp be in a ceiling void,
Here in JHB we reach highs of mid 30's but it can get to 40 but not often, so I guess a ceiling for a safe bet of maybe 50 degrees ?

I mean you can sweat proper in a roof.

Anyone got a more acurate number for ceiling tempretures ?

This helps with selecting cables etc for the CCC amougst others but most common factor for me at least is ambient temp.

I use the correction factor of 40degrees as I feel a bit of diversity can be applied but want to hone on this.
