General contractor with a separate electrical website: one Google Business Profile or two?

[WebProfitLab]

We're one company in Washington State doing general contracting and electrical work. The electrical side has its own website and domain, separate from the main contracting site. We're about to verify our Google Business Profile, and I'd like to get the structure right first.
What I'm unsure about:

• Is a second profile for the electrical side ever allowed when it's the same company, or would Google treat it as a duplicate?
• If it has to be one profile, would you link it to the main site and send electrical visitors to the other domain from there, or link it to whichever site brings in more of the calls?
• Does it matter that electrical work needs its own state license here?

Not trying to game anything. I just don't want to set it up in a way that gets the profile suspended later.
