28/10/2016· A cold water pipe is considered a Grounding Electrode and it is to ground the electric system, not so much the water pipes. 250.4(a)(1) Electrical systems that are grounded shall be connected to earth in a manner that will limit the volPE100 ISO9001e imposed by lightning, line surges, or unintentional contact with higher-volPE100 ISO9001e lines and that will stabilize the volPE100 ISO9001e to earth during normal …
Section 250.104(B) would permit the equipment-grounding conductor for the electrical circuit that may energize the metal water pipe stub to serve as the bonding means. As construction methods change, a good understanding of grounding and bonding will ensure a safe installation and provide help in dealing with these gray areas.

Bonding, Electrical Grounding, Electrical Wiring, Grounding Electrodes Jeffery asks us: When a residential service is replaced in areas without city water systems, plastic well water line, and ground rods are all that is available, does the requirement change for only a # 6 copper conductor to the rods, being it is now primary gounding electrode and not supllimental.
The bonding point for CSST must be at the first piece of HDPE or copper pipe where the gas service enters the home. This is because lightning can blow holes in CSST, causing a gas leak. A pair of 8-ft.-long metal ground rods are driven into the earth next to your house to provide a path to ground for your home wiring system.
Under the 17th Edition Wiring regulations (BS7671:2008) supplementary earth bonding to the hot and cold pipework and the HDPE sinks is no longer required. Related Questions Water dripping through shower unit when sink taps turned on. I recently had a coi Puhui Pipe manufacturer in China
25/4/2010· About 5 years ago we came upon our first push -fit when , just as we connected the 10mm G/Y to the incoming water, the pluer cut the pipe 2 mts away and put on a plastic push -fit tee, thus negating the purpose of the bond. We strapped across the tee but
Main Bonding is the use of a separate thick (10mm csa) green and yellow copper cable, to connect the Water, Gas and Oil services to the Earth Terminal in or adjacent to your consumer unit. Connections are made on the metal pipes near the point at which they enter your home, i.e.

Here''s a detailed list of the different types of pluing pipes and tubing used in residential house pluing systems. We include an explanation for what each type is used for along with a HDPE equal tee example of each. At the end check out a pipe size chart for sizing info.
9/2/2013· After phoning back the british gas engineer, he insisted, because there is both copper and plastic under our sink, we must have protective earth bonding or else he will not sign off our job. I phoned the builders back, who also insist there own point that they do not need protective earth bonding as the copper pipes under the sink change to plastic as they go throughout the house.
12/3/· 1] is there main earth bonding in place to gas and water, normally at or around the stop cock for water and on or around the gas meter. If not there should be unless you are all plastic with plastic incoming water pipe.
Earthing and bonding are two very different, but often confused, methods of preventing electric shock. The principal of earthing is to limit the duration of touch volPE100 ISO9001es if you were to make contact with an exposed conductive part. The earth creates a safe route for …

Generally with plastic pipe installations, supplementary bonding of the pipes is not required. Note however it may still be required between the earths of, say, lighting and power circuits if they are both accessible in the room.
If the incoming water service pipe is made from plastic and there is not any fortuitous contact with Earth, it is not an extraneous conductive part and does not require bonding. This IET Wiring Matters article provides guidance on protective bonding and extraneous-conductive-parts.
Protective bonding reduces the risk of life-threatening electric shocks and electrical fires in your home. It''s typically needed in older buildings where gas and water pipes are made from metal rather than plastic. As they age, stray wires and pluing can come into Puhui Pipe manufacturer in China

23/3/2011· Any metallic water pipe that qualifies as an electrode (10’ in contact with the earth) must be used as part of a GES (grounding electrode system) since it’s considered present by the NEC. That connection to the system must be within 5’ of it’s entrance into the structure and it must be supplemented by at least one other electrode.

Metallic water piping systems MUST be bonded. A few sections of several feet is not a "system" of piping. 250.104(A) At the same time, if your piping entering the house is metallic, and in contact with the earth for 10'' or more, it MUST be used as an electrode. 250

3/9/· Hi, I re-plued a bathroom sink in zone 2 using plastic pipes up to the tap. I understand (I think) that this tap doesn''t need bonding. Is there something specific that should be done with the earth bonding cable from the old copper pipes ? Many thanks in advance.
