100AMP Breaker Panel - Wiring Advice

Hello!

Photo of panel to be linked below as a reply.

I have taken on the task to wire a new 100AMP main electrical panel.

Have the permits from ESA. Want to make sure it's top shape.

Change out is from an old 100AMP Fuse box.

I have the two main legs feeding into the 100AMP breaker. The neutral is fed to the neutral bar. The GEC to the ground at the top.

I've used dielectric grease on connections thus far.

I would just like to confirm that this is a good setup before I start placing in the breakers.
Thanks folks!

The GEC must terminate on the neutral bus.

Where did you get that panel? It looks like one from USA. If it is from USA, I don't think it will pass ESA. In Canada the main breaker is in a separate compartment from the branch breakers.
Is the front panel in two pieces or one? If it is in two pieces you are probably fine.

ESA is the Electrical Safety Authourity in Ontario so I guess that needs to be cleared up.

Also
Why is the neutral all taped? Is that a bare wire? It will not pass as a neutral if it is.

I could be wrong about the bare neutral. Ignore that comment. But white tape instead black should be used.

Grounding bushing needs to be bonded to the neutral or ground bus.
Ground wire should be taped green.

Hi everyone,

I am located in Ontario. I will change that in my profile.

The main breaker is in a separate 'top' compartment. Others are in the bottom. It is a Siemens 100AMP, 24 circuit main breaker from Rona. Folks their seemed confident it would pass ESA.

I have wrapped neutral in white tape. Also, I have bonded the GEC to the ground bus bar with a #3 bare copper wire. Adjoined to that is a grounding wire from a water main pipe. I've wrapped them in green tape.

I have been using this image as a guide:

Regardless, the GEC still must be terminated ON the neutral bus and not on the ground bar or a lug bolted to the panel box. If this is your main panel the neutral bus then gets bonded to the panel box. I am assuming this is a common requirement between the NEC and Canadian codes, but since we now know this is in Ontario there might be some differences in codes, joed would know.

Thanks for the advice!

I now have the GEC and the water main grounds terminating on the neutral bus (which is bonded to the panel).

wrapped the main neutral in white tape. All the grounds in green tape.

What is the lug used for (if anything) that I had the GEC terminating to originally?

Here is a URL to the setup now:

GEC to Neutral Bus Bar (black but with green tape)
Water main ground to Neutral Bus Bar
Bolted lug (top of box) to Ground Bus Bar (as suggested by Tolyn Ironhand [if I understood correctly]).

I'm thinking to connect the ground bus bars together and using 3 gauge wire. Then connecting these with a 3 gauge wire to the neutral bus bar. While it's not needed (as I understand) this way I do not need the panel to conduct a surge from the ground bars to the GEC.

Thanks for the help again.

I don't know why you have all those wires on the right. I would just put the ground into the lug and install the green screw to bond the neutral and ground.

joed, like I said in post #11, there may be some differences between the NEC and Canadian codes. By the NEC the GEC must be terminated on the neutral bus and not on the ground bar or a lug bolted to the box and then the neutral bus is bonded to the box.
