![]() ![]() The most common type of outlet in older homes is the two-hole outlet, which can accommodate two separate plugs. This fee varies from one city to another. In most situations grounding a 200 amp service simply involves adding a second ground clamp where the ground wire attaches to the water pipe.Ī hydro inspection fee of $96.00 is required on any electrical work. That cost can increase depending on how far the incoming wires are from the main panel and how close the water pipe is to the main panel. The cost of upgrading an electrical service from 60 amp to 100 amps starts at around $800.00 which includes permits. When plastic piping enters into the house with a 100 amp service, double ground rods are required connected by a continuous wire uncut. A tag on the service panel indicates who did the electrical work, and verifies that it has been inspected and approved by Ontario Hydro. Electricians belong to the Hydro Authorization Program. It is important to ask for proof of certification from the province of Ontario. When a house needs an electrical upgrade or if the system needs to be grounded, a qualified electrician should do the work. Under today’s standards it is to be connected before the first shut-off valve leading into the house. It is quite common in older homes to find the grounding wire connected to a metallic copper or galvanized plumbing supply pipe that is close to the electrical panel. When the water supply pipe is plastic, the ground wire runs from the neutral bus bar to a pair of metal rods outside driven four feet into the ground. The copper grounding wire is bare because it has no need for insulation since it is already grounded. The wire is attached to the pipe with a ground clamp made of copper, bronze or brass. According to 2018 CEC 10.114, a 200 amp service calls for #6 CU (#4 AL) conductor for grounding conductor, and bonding 100A-200A (table 16). A 100 amp service requires a bare #6 copper grounding wire which runs from the neutral bus bar to the metal cold water supply pipe that goes into the ground. In order to ground an electrical system, all of the white neutral wires are connected in the main service panel to a metal strip called a neutral bus bar. The most common way to ground an electrical system is by attaching the grounding wire to the cold water pipe. It services all of the electrical outlets and should also ground all of the light fixtures. The ground wire is the biggest electrical safety feature in a house. This can result in an electrical fire or electrocution. Without grounding, the electricity is live and will transmit a charge to a person or object that comes in contact with it. Grounding is an essential safety precaution to minimize shocks and prevent damage from lightning, short circuits and faulty wiring. Electrical systems must be grounded so that electricity can be harmlessly discharged into the earth.
