See full version: Push-to-Reset Circuit Breaker
This Marine Circuit Breaker is the same resettable breakers that we use in our custom marine panel assemblies . Our thermal breakers come in four sizes: 5A, 10A, 15A, and 20A. They trip off and can be reset right from the front of the panel.
Breakers can replace the failure-prone and annoying to replace fuses for your branch circuit protection. Remember to protect the primary feed from the panel with a larger in-line fuse or circuit breaker close to the battery.
They are easy to install with a 3/8″ drill bit, our breakers have a small form factor to fit more switches in a smaller space. At only 1.16″ x 1.53″, they are some of the smallest in the industry.
Size: 7" W X 12" H X 4" D
Has large DC circuit capacity and AC section including two load groups and a source selector switch for two shore power lines and a 15kW generator. Pre-heat and start-stop controls are standard. Additional system capacity can be obtained by incorporating model ES-6, ES-7 or ES-8. more
Size: 20" W x 15" H x 6" D [links]
To change circuit breaker value mix or location, advise us the breaker arrangement. (Order forms listing all options are available online - see "Download PDF Order form" link below each product description.) Allow 3-5 days additional lead time to complete the modification.

Yes, This comes up in the ordering process, but most of the time it happens during the initial estimation of a new construction project when sizing a cable is most important.
Table 310.16 ampacity for 8 THHN is 55A at 90°C in a dry location: Use the THHN 90°C column. here
Working on anything we can help you with today?
When conductors are bundled together, they lose some of their ability to dissipate heat. In the NEC, the allowable ampacity starts dropping when four or more current-carrying conductors are bundled together for more than 24 inches [310.15(B)(2)(a)] (Fig. 2). here
This is in accordance with their ampacities as specified in 310.15. Section 240.4(A) through (G) contains rules that modify the general requirement and permit conductors to be protected in a manner other than their ampacities from 310.15, including:
Re: Ignition switch wire sizes and fuses
The red wire with purple stripe is sourced at the engine and is fuse protected there with a 20 amp fuse.
The purple wire (switched 12v) should only power the gauges. tach for sure.
Use the following links to help you rewire. The fuse in the engine protects the ignition switch. The accessory power is for the gauges do not use it for powering all of your other equipment. Run a separate wire from the battery to the console power distribution panel. If you want it switched you will need to use a relay. [links]
I have a Victron 150/45 MPPT with a 500w solar panel.
I'd like to put a 15A PV fuse with a disconnect switch between the MPPT and the solar panel. Another option would be a 15A DC rated circuit breaker. Please not the emphasis on DC rated, do not use AC circuit breakers for DC circuits.
What size fuse/breaker should I use? Or should I use bigger wire than the manual specifies so I can use a 50A fuse? [links]
