Final answer:
In an RV, if the distribution panel has a bonding strap or screw, it should be removed or remain in place based on whether the panel is a main service panel or a sub-panel, to ensure proper grounding and bonding as per the NEC. Always follow the manufacturer's instructions and consider consulting a professional electrician for safety.
Step-by-step explanation:
When dealing with a distribution panel intended for use in an RV, the presence of a bonding strap or bonding screw indicates the necessity to ensure proper grounding and bonding of the electrical system. In an RV, the electrical system is typically separated from the chassis for safety reasons, and the neutral and ground should not be connected within the distribution panel unless it is designed as a service entrance panel.
If the distribution panel is intended to create a separation between the neutral and ground, then the bonding strap or screw must be removed to prevent any potential electrical hazards. This separation avoids potentially dangerous situations where a short circuit could energize the body of the RV. However, if the panel is used as the first means of disconnect and is thus considered a main panel, the bonding screw or strap must remain in place to ensure that the ground and neutral are properly bonded. In any case, it is crucial to follow the manufacturer's instructions and applicable electrical codes.
Please consult a certified electrician or refer to the National Electrical Code (NEC) for further guidance related to RV installations and safety requirements.
