∙ 12y agoIf the service stack is supported by a support structure and the utility feed drop is not supported from the conduit, the size of the conduit can be 1 1/4". If the service stack is used to support the utility feed drop then the conduit has to be 2" schedule 40 conduit. The reasoning behind this is that if in a storm a tree limb falls across the service drop, the lighter weight conduit could bend and pinch the wires in the stack and short out. This would be ahead of the main service breaker and the only protection for the wire would be the primary fuse at the transformer. Theoretically this amperage could rise to 50000 amps before the primary fuse blows. A schedule 40 service stack if supported, as the code requires, will withstand most tree falls. What is most likely to happen is that the utility connectors will pull apart leaving the service stack intact.

Using THHN wire and EMT conduit, you need 1 inch for 3 conductor service or 1 1/4 inch for 4 or 5 conductor service. These are minimum size conduit and I recommend you not use the 1 inch regardless and use 1 1/2 inch conduit for a 5 conductor service.

As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

A 100 amp residential service requires a size #8 copper wire, it should be insulated in green.
The wire that is used for connecting the ground rod or plate to the electrical distribution is governed by the size of the electriclal distribution. In Canada a #6 bare copper is the minimum size for a 200 amp service.

A new home will typically have a service entrance with a minimum current rating of 100 amps to accommodate the electrical demands of modern households. It's important for the service entrance to be properly sized to ensure safety and reliability of the electrical system in the home.
According to the NEC, a minimum of 1.5-inch conduit is required for a 100 amp service. It is important to follow local codes and regulations which may vary. Consulting with a licensed electrician is recommended for proper installation.

No, but there is generally a minimum opening deposit and minimum balance to keep the account free. Most commonly it is $100 to open and a minimum of $300 to avoid a $3 a month service charge.
No, each size service needs its own meter base.
