3phase kw to singlephase kw

[bjn21]

I have measured kW on each phase of my circuits in a panelboard. How do I determine the kW total on one 3 phase circuit?
Do I sum the three phases readings together? or average them?

Example:

Phase Reading	Breaker	Breaker	Phase Reading
A:3, B:4, C:3	1	2	A:3, B:3, C:3
A: 5, B:5, C:5	3	4	A:3, B:4, C:3
A:1, B:1, C:0	5	6	A:3, B:4, C:3
A:1, B:1, C:1	7	8	A: 5, B:5, C:5
All zero	9	10	All zero

So what would my breaker kW total be for breaker 2 for example? 9kW or 3kW?

Welcome to the forum.

That's the good thing about working with kW: they simply add.

3 x 3kW = 9 kW.

Thank you!!!

Good to be on here, treasure trove of information

Been meaning to join for ages since I am a junior engineer and I always have questions haha
