Fuses if i use 2 20 amp fuses, will that be 40 amp? what about circuit breakers, i dont see too many on 12 v.d.c. apps? THANK YOU.

#8 wire for a 40 amp breaker is fine for what you have. You could put a 45 in if you wanted to and #8 wire would still be fine.

What kind of cuircuit breaker is it 40 or 30 amp breaker it makes a big diference for 30 amp breaker you need # 10 wire
for a 40 amp you need # 8 wire
hope this will help.

Why don't you simply reposition the circuit breaker?You can replace the circuit breaker with a fuse if you wish but do not go up on the rating. Right off hand, I don't remember the rating on your circuit breaker. But, it it's rated at 40 amps, do not replace it with a 45 or higher rated fuse. The reason is that the circuit breaker is there to protect your wiring harness. If you go up on the rating of the fuse, it allows too much current to flow and your wiring harness is in danger then. Got to almost any automotive parts house and you can buy an inline fuse holder. I'd get one of those Maxi fuse holders, not the little minifuse holders of the glass tube type fuses.

Good Luck

Hi I would suggest 40A (i know guys will disagree) but you shouldnt be running at full 50A. Fuse are often rate at 50% - 75% of the actual consumption. By the way, 8 guage @40A will give you about a 2% drop at 5 feet. Maybe consider heavier for 40A?? Just a suggestion

As long as it is wired with at least #8 wire your 40 amp breaker should be fine. The 50 GFI could not pull over 40 amps from the main panel.

relays are normally in the fuse panel on the left side of dash by knee.

Fuses and Circuit Breakers Location and Values
NOTE: The headlamp switch (11654) has an integral 20-amp circuit breaker.

• The combination instrument panel fuse and circuit breaker panel contains most of the fuses and circuit breakers used in the system.
• The fuses and circuit breakers are color-coded by amp rating.
• The locations and values of the fuses and circuit breakers not contained in the panels are shown in the following chart.

On the 40 amp breaker, you should be using 8-3 w/ground. 10-3 w/ground will work on the 30 amp breaker. 12-3 w/ground is used for 20 amp circuits. Your new heater should have the electrical requirements listed in the user/installation information.

Diagram for aosmith motor b381 is here: http://www.electricmotorwarehouse.com/IMAGES/B381_connection.htm

However, I believe that this motor will be more efficient at 230v depending on load conditions. At 115v this motor will draw more amps and tend to run hot, but situation rules. Enjoy

Hi,

The only possible check that could be done without removing/opening the Audiovox TV would be to check for the presence/absence of supply power/voltage depending on how the TV is powered (12VDC or 120 VAC). Normally, there would be an fuse and/or circuit breakers.for the RV's entertainment system including the TV.
The 120-volt circuit breakers and 12-volt fuses are located in the same compartment. These devices interrupt the power if the circuit is overloaded.The 120-volt circuit breakers include a 30 amp main breaker and several smaller breakers for individual circuits. If a circuit breaker is tripped, look for an overload on the circuit, then reset it by turning the breaker OFF and then turning it ON. Do not try to reset a breaker the second time without locating the overload problem. The 12-volt fuses protect individual circuits. If the circuit is overloaded, it will blow the fuse and the fuse must be replaced. Check the circuit for an overload and replace the fuse with the same type or amperage rating.

If the above checks out, then problem is internal to the unit and would require removal from its current position.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
