Service Entrance SE Adjustable Wire Holder. The bonding connection is typically made at the hot-water side of the piping to ensure continuity of the required bonding for metallic piping within the structure.
The water heater itself my have insulated joints to reduce electrolytic corrosion and the bonding jumper would provide a path to ground in case any hot water pipe got electrified accidentally.
Water heater wiring for bonding. Where hot and cold water pipes are electrically connected you need only one bonding jumper to either the cold- or hot-water pipe. The plumbing if metal or bonded as part 4 above will serve as an adequate ground for safety purposes. The bonding jumper may be required to ensure a reliable bond in a metal water piping system.
A ground wire sized for the water heater power conductors may be run separately and also protected from damage from the ground screw on the water heater to the panel ground bus or to any point on part 1 or part 2 or part 3. Attach Bond Wire From Pool Pump Here Access Content. Kit includes two brass ground clamps and copper conductor.
Because your water heater has dielectric unions so the hot and cold plumbing are isolated from each other. Which means if you grab a hot and cold handle you could complete a circuit. Warranty will be void if system is not properly bonded.
This is frequently done at the service panel. While a bonding wire is not always required by codes the part is only 10 and very easy to install so its not a huge investment to add one to your water heater. It typically has two brass clamps with a thick copper wire strung between them.
GROUNDING AND BONDING Home Inspector ConsultingHome Conductor in a 240volt circuit such as the circuit for an. A conventional electric water heater will come with a black wire and a red wire which are connected to the wires of the same color as described above. Electrical Metallic Tubing EMT 1-Hole Snap Strap Case of 10 1-14 in.
Without the jumper there is a break between the hot water and cold water pipes in the system which potentially disrupts the continuous grounding pathway of the. One clamp is placed on the cold water pipe while the other goes on the hot water pipe. Insulated hot water pipes bonded metal piping to ground installed GFCI RCD receptacle for the tankless heater.
The cold and hot copper water lines were isolated from each other at the water heater by dielectric unions an insulating bushing built into the union and then connected from the dielectric union into the tank using galvanized or black-steel nipples. Read Or Download The Diagram Pictures Heater Wiring For FREE For Bonding at 360CONTESTDEMOAGRIYACOM. The transition from nonmetallic water pipe inside the walls to a plumbing fixture such as a sink toilet or a hose bibb is accomplished by using a copper 90-degree elbow and a short piece of copper tubing.
Still there are electricians and local building codes that vigorously defend the water heater bonding wire as a proper safety measure. Hot water pipes were insulated from the he. Service Entrance SE Cable Sill Plates.
The Southwire water heater grounding kit is designed for residential water heater use but can be used across any continuity break in residential plumbing. He probably wants clamps on the inlet and outlet pipes of the water heater with a 6 wire running between them. Another function of the bonding wire is to maintain the electrical grounding pathway on the water pipes.
The ground wire is attached to the green ground screw which is in the same wiring junction box compartment which is built into the top of the water heater. The reasoning is that the metal casing on the water heater itself is thought to be sufficient to complete the continuous grounding path between the cold water and hot water pipes in the home. See Prop 65 WARNINGS.
Water Heater or Meter Bonding Kit. Some experts believe a bonding jumper helps water heaters last longer by reducing corrosion in the tank caused by electrolysis. The copper elbow is attached to the nonmetallic water pipe by solvent cement heat fusion or by metal corrosion-resistant compression fittings.
Run the bonding wire from a point near your water heater a convenient spot if you have a gas-fueled water heater to an exit point where the wire can be bonded to the grounding wire that leads to the exterior grounding electrodes. A bonding wire is an external part that is attached to the water heater. It should be noted that the National Electric Code does not require a bonding wire on a water heater.
This bonding is essential to maintain continuous ground path. Otherwise use a single bonding jumper sized per 250104A1 to bond the hot- and cold-water piping together – Mike Holt. Bonding 7 Water Chemistry Maintenance 8 Heat Pump Features 9 Heat Pump Operation 10 Control OnOff 10 control box of the heater for the bond wire to be attached.
Bonding the plumbing attempts to keep the hot and cold plumbing at the same electrical potential. Occasionally you might see a jumper from the cold side to the hot side of the water heater and you may even see a jumper to the gas piping. Houston Home Inspector discusses Bonding of Water heater.
If this bond is not in place its possible for the hot and cold plumbing to be at different voltage potentials.
