How do you ground a 200 amp service with no water main?

You need two forms of grounding according to the code. Grounding to the water main is typically the best ground in a building. If you don't have a water meter you can add an extra ground rod.


How do you install a ground rod to a house meter base?

Unless otherwise specified you need a 5/8th inch by 8 foot copper clad rod. A great trick is to drive it in at a 45 degree angle and bend it up as you go so it ends up straight after it drive in all the way. This keeps you from hitting hard pan and keeps you from having to get on a ladder to drive the rid which can be kinda dangerous. Leave about 4 inches out of the ground for you ground clamp. For a 200 amp service use #4 armored ground. For 125 amp or 100 amp you can use #6 armored ground wire and an armored ground clamp. The NEC allows that for ANY connection to ground rod, #6 solid copper is the largest conductor required. The ground rod is SUPPLEMENTAL, and only in rare circumstances is the ground rod your primary ground. The sizes given above are for your primary grounding connection, such as a metal water line.


What size ground rods for 800 amp electrical service?

You will need two 8 foot ground rods. One placed under the meter base and another one placed 6 feet to the side next to the foundation. If this is a home I highly recommend you install a 200 amp service instead of a 100 amp service. Not much more expensive and you will have plenty of room for growth.


How many grounding clamps are permitted on one ground rod?

As long as the clamp is of an approved type only one is needed per ground rod.


How many ground rods needed for a temporary service at construction site?

The NEC makes no provision for using 1 ground rod even on a temporary service. According to the NEC you must use 2 ground rods. However in my area we are allowed by the local inspector to use just 1. Call your local inspector and see what he requires as he has the last word on this.

What size ground on 200 amp service?

In Canada it is a #6 bare copper conductor that connects the grounding rod or plate to the neutral point in the distribution panel.


What wire size to use from breaker box to earth ground rod?

We recommend using a #6 copper wire for the connection between the breaker box and the earth ground rod. This size wire is commonly used for grounding purposes and is sufficient for carrying the electrical current safely to the ground rod. Be sure to consult with a qualified electrician to ensure the proper materials and installation for your specific situation.

What is rod earthing?

It is the installation of ground rods at a service entrance distribution to bring the relative resistance to ground to be within 5 ohms of the utility's distribution network. This grounding system is then connected to the service distribution with a calculated size wire and connected to the distribution at a point within the distribution panel, where the service neutral wire joins the neutral bus bar.


What is the minimum size of service entrance conductor?

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.

What size ground wire for a 200 amp service panel to the water meter?

For a 200 amp service panel to the water meter, it is recommended to use a 4 AWG copper wire or 2 AWG aluminum wire as the ground wire. This will provide sufficient grounding capacity for the service panel and meet code requirements. Be sure to check local electrical codes for specific requirements in your area.
