Seriously, I don't like the term ethical hacker. Professional experts who access systems using skills other than ones known to the average user are not hackers, a term connoting persons hacking away at something until they gain access to what is needed. An expert who legally utilizes skills in order to access systems does so in a methodical approach.
What makes it legal is the owner of the system requests their expertise to assist in accessing areas where they've lost capabilities in doing so. There's no reason to tie the word "ethical" to a negative term in order to indicate the opposite of that term which refers to IT professionals who already carry titles such as Systems Engineers, Network Analysts, Security Analysts, etc.
Hackers are criminals. There is nothing "ethical" about hacking. You are gaining access to a system in which you do not have permission to access. Would you ever refer to a locksmith as an ethical burglar?
