I inspected a GE sub panel with a 60 amp breaker from the main panel. I do see the 4 wire feed. Is this sub panel required to have a bonding strap?
Any additional information would be appreciated. Thanks.
The green screw at top right is, should be, the bonding “strap”.
Not in Canada only the primary panel is it required .
Neutral and ground are separate through the rest of the system .
The bar on the right is the EGC bus and must be bonded to the enclosure thus the green screw.
The equipment grounding conductors in a RDP don’t need the bonding screw/strap in Canada?

Threads go sideways when you delete text. :roll:
So you don’t bond the EGC’s to the panel if its a sub panel? That is strange indeed.
Why what is strange . it keeps the ground from carrying any of the load that should only be carried by the neutral
Wow I can vaguely remember that thread. 
I had to find it. Roy had me questioning myself. 
:shock:
Well yeah, that is why you separate them and isolate the neutral from the panel.
Here though, the EGC’s still get bonded to the enclosure.
Right?
I have no idea we also isolate the grounds and neutrals in our panels .
I see pictures in USA both in the same buss .
You don’t bond the grounded and grounding conductors in the service panel?
Sorry if I keep asking the same question in different terms. I am just making sure I understand you correctly.
Juan, I think you and Roy are talking about two different things. Bonding and Grounding
Actually, I believe Roy is just misunderstanding Juan.
EGC’s and neutrals are required to be separate/isolated from each other as Roy is stating, however, the EGC’s must be bonded to the enclosure as Juan is pointing out.
I believe this holds true even in Canada.
I tried to be as clear and technically accurate as I could in my questions.
Sorry Juan and thanks Jeff .
You guys are correct and I just could not see what Juan asked .
Thanks to all for putting up with my not understanding … Roy
