 | | Bussmann Series 187 MRCB (Marine Rated Circuit Breaker) | | Important information about the Bussmann Series 187 MRCB Circuit Breaker | The Cooper Bussmann Series 187 MRCB Thermal Circuit Breaker is based on the T-1 Thermal Circuit Breaker that was designed and developed by Blue Sea Systems' engineers in 1999. In 2003 Cooper Bussmann acquired the T-1 tooling and patents from Blue Sea Systems. In 2005 Cooper Bussmann will introduce the 187 Series Thermal Circuit Breaker based in part on the T-1 design. Using their long experience in thermal circuit breaker design, Cooper Bussmann improved the original T-1 internal mechanism & current path via several design changes. The 187 Series retains all the features that made the T-1 so popular - robust construction, easy mounting, large terminal studs and attractive styling. Cooper Bussmann has certified that the 187 Series Thermal Circuit Breaker meets SAE J1171 for ignition protection and has a 5,000 Amp interrupt capacity per ABYC E-11 at 12 VDC. The yellow handle and text of 187 Thermal Circuit Breaker clearly distinguish it from the T-1 Circuit Breaker's red handle. Please visit our website for information on the T-1 recall initiated in 2003. | | | | | |

 | | Navigation Light Switchin for Vessels Under 20M | | | | | The possible switch configurations for navigation lights vary greatly depending on the vessel size, type, and purpose. This article addresses the most common configurations for smaller vessels.
ABYC standards state that one switch, or position of a switch, will turn on all of the navigation lights required for the vessel while underway. Another switch, or position of a switch, will turn on the anchor light. This allows the use of either 2 switches or a 3 position switch with one off position.
The most common configurations of lights are: | 1. | | A bicolor light with an all-round (360°) white light | | 2. | | A bicolor light with a 135° stern light and a 225° masthead light and a 360° anchor light | | 3. | | Two sidelights with an all-round (360°) white light | | 4. | | Two sidelights with a 135° stern light and a 225° masthead light and a 360° anchor light | | 5. | | A masthead tri-color light with a 225° masthead light and a 360° anchor light |
These can be broken down into 3 combinations:| A. | | A bicolor or two sidelights and an all-round white light | | B. | | A bicolor or two sidelights with a 135° stern light and a 225° masthead light and a 360° anchor light | | C. | | A masthead tri-color light, a bicolor or two sidelights, a 135° stern light, a 225° masthead light, and a 360° anchor light |
