Power cut? That's disgusting (4)

Ross

I believe the answer is:

phew

I'm a little stuck... Click here to teach me more about this clue!

'that's disgusting' is the definition.
I can't judge whether this definition defines the answer.

'power cut?' is the wordplay.
'power' becomes 'p' (symbol in physics).
'cut?' becomes 'hew' (hew can mean to chop or cut).
'p'+'hew'='PHEW'

Can you help me to learn more?

(Other definitions for phew that I've seen before include "Expression of relief" , "Gosh, that's a relief!" , "Exclamation of relief" , "I'm overheating?" , "Good gracious, its hot!" .)

I've seen this clue in The Irish Times.
