Discussion Overview
The discussion revolves around connecting a 240v water heater to a new DPST timer switch, specifically the Intermatic EH40, after the original SPST switch failed. Participants explore wiring configurations, safety considerations, and the implications of different electrical standards.
Discussion Character
- Technical explanation
- Debate/contested
- Conceptual clarification
Main Points Raised
- One participant suggests leaving the neutral line intact and connecting one side of the DPST switch to the hot line, but advises waiting for an electrical expert's confirmation.
- Another participant clarifies that the switch in the attachment is indeed a DPST and outlines how it should work with the specified terminals.
- There is confusion regarding the terminology used in the switch's documentation, particularly the term "charge area," which is debated and clarified as referring to power supply voltage in different languages.
- Participants discuss the wiring color codes for 240v systems, noting differences between US and international standards, including the use of black and red wires for hot lines and white for neutral.
- One participant raises a question about how the original circuit was wired with an SPST switch, suggesting that it might be possible to replicate the connections on one side of the new DPST switch.
- Another participant mentions that in some countries, a single phase of a three-phase system may be used, which could explain the wiring configuration.
- There is a discussion about the implications of switching both power lines for safety and adherence to local electrical codes.
Areas of Agreement / Disagreement
Participants express various viewpoints on wiring configurations and safety practices, with no clear consensus reached on the best approach to connect the timer switch to the water heater. The discussion remains unresolved regarding the specifics of the wiring and the implications of different electrical standards.
Contextual Notes
Participants note potential confusion arising from the switch's documentation and the differences in electrical standards across regions. There are also mentions of varying interpretations of terminology used in the switch's instructions.
