1. はじめに
This manual provides essential information for the safe and correct installation and use of the SIEMENS ECGB14 Ground Bar Kit. The ECGB series ground bars are designed for use in Siemens EQ and Ultimate brand load centers, specifically those with catalog numbers beginning with E, W, or G.
インストール前にこのマニュアルをよくお読みになり、今後の参照用に保管してください。
2. 安全情報
WARNING: Risk of electric shock. Installation and servicing of electrical equipment should only be performed by qualified, licensed personnel. Failure to follow these instructions can result in serious injury or death.
- 電気機器の作業を行う前に、必ずメインサービスパネルの電源を切断してください。
- 絶縁手袋や安全メガネなどの適切な個人用保護具 (PPE) を使用してください。
- 緩んだ接続や潜在的な危険を防ぐために、すべての接続がしっかりと固定されていることを確認してください。
- Verify that the ground bar is compatible with your specific Siemens load center model.
- 地域および国の電気規則をすべて遵守してください。
3. パッケージ内容
The SIEMENS ECGB14 Ground Bar Kit typically includes:
- 1x SIEMENS ECGB14 Ground Bar
- Mounting screws (quantity may vary, typically two)
- Bonding strap (for main panel applications, if included)

4. セットアップとインストール
Follow these steps for proper installation of the ECGB14 Ground Bar:
- 電源切断: Before beginning any work, ensure that the main power supply to the load center is completely disconnected and locked out according to safety procedures. Verify with a voltageテスター。
- 取り付け場所の特定: Locate the designated mounting points within your Siemens EQ or Ultimate load center for the ground bar. These are typically pre-drilled holes.
- Mount the Ground Bar: Position the ECGB14 ground bar against the mounting points. Use the provided mounting screws to securely fasten the ground bar to the load center enclosure. Ensure it is firmly attached and does not wobble.
- Connect Ground Conductors: Each of the 14 terminal openings is designed to accept No. 14-4 AWG copper (CU) or aluminum (AL) conductors.
- Strip the insulation from the ground wire to the appropriate length as specified by the wire manufacturer or local codes.
- Insert one ground conductor into each desired terminal opening.
- Tighten the screw firmly to secure the conductor. Refer to the load center's documentation or local codes for specific torque requirements.
- Bonding (Main Panels Only): If installing in a main service panel where the neutral and ground are bonded, use the provided bonding strap (if applicable) to connect the ground bar to the neutral bar. Consult local electrical codes for bonding requirements.
- 最終検査: Double-check all connections for tightness and ensure no bare wires are exposed outside of terminals. Confirm that the ground bar is properly installed and all safety precautions have been observed.
- 電力を回復する： Once installation is complete and verified, restore power to the load center.
5. 操作
The SIEMENS ECGB14 Ground Bar functions as a common connection point for all equipment grounding conductors within a Siemens EQ or Ultimate load center. Its purpose is to provide a safe path for fault currents to return to the electrical service entrance, thereby protecting against electric shock and equipment damage.
Once installed and wired correctly, the ground bar operates passively, ensuring electrical safety by maintaining a continuous and low-resistance grounding path.
6. メンテナンス
The SIEMENS ECGB14 Ground Bar requires minimal maintenance. However, periodic inspection is recommended to ensure continued safe operation:
- 目視検査: Annually, or as required by local codes, visually inspect the ground bar and all connected wires for any signs of corrosion, loose connections, or damage.
- 気密性チェック: With power disconnected, carefully check the tightness of all terminal screws. Over time, connections can loosen due to thermal cycling. Do not overtighten.
- クリーニング： If dust or debris accumulates, disconnect power and use a dry, non-conductive brush or vacuum to clean the area around the ground bar. Do not use liquids.
WARNING: Always disconnect power before performing any maintenance or inspection on electrical components.
7。 トラブルシューティング
The ECGB14 Ground Bar is a passive component and typically does not "malfunction" in the traditional sense. Most issues related to grounding are due to improper installation or external factors.
- 緩い接続: If you suspect a grounding issue (e.g., flickering lights, mild shocks from appliances), first check for loose connections at the ground bar terminals. Ensure all wires are securely fastened.
- 腐食： Inspect for any signs of corrosion on the ground bar or wire terminals. Corrosion can increase resistance and compromise the grounding path.
- 配線ミス: Verify that all ground wires are correctly terminated to the ground bar and that the ground bar is properly bonded (if in a main panel) or isolated (if in a sub-panel) according to code.
- 専門家によるサポート: If grounding issues persist or you are unsure about any aspect of your electrical system, consult a qualified electrician. Do not attempt repairs if you are not competent to do so.
