The fuse should always be the first thing a power supply hits when it gets to a circuit. The reason is pretty simple. In the event of a fault that blows the fuse, the power is isolated to where it entered the circuit, thus the whole circuit is protected. Using other configurations could allow the supply voltage into other parts of the circuit unexpectedly. There are situations where it's good to fuse both the power supply and the load, but that's another question. more

In most cases, I would prefer to put the fuse immediately after the main power switch. That way, with the power switch off, both terminals of the fuse are "dead", so there is no shock hazard while changing the fuse, providing the switch is off. more

For plug-in equipment the order is less important, as you can unplug the equipment while changing the fuse. [links]

It’s a 45a double pole switch probably. Doesn’t have a fuse. Protection is upstream at your consumer unit here

[Bruce Wagner]

This depends on the fuse requirements for the oven, e.g. it could require a dedicated 32 amp circuit and if this is the case the fuse is on the consumer unit so all you then need is a double pole 32 amp isolation switch which is normally a big red switch, easily recogniseable.
As a general rule if your built in oven has more than 1 door, eg double oven then generally they need a 32 amp fuse because you can run 2 ovens or an oven and a grill at the same time which requires more current than a 13 amp fusedcswitch or plug socket supply can cope with more

Most single door ovens require a 13 amp fuse. If this is your type then it should be plugged in or wired to a 13 amp fused spur however you may not be able to see this as it could be somewhere you cannot see, eg behind the appliance. So the elrctricisn may have fitted a switch to make it easier to isolate the oven. more

Run bus bars for the other add-ons. I have a dual buss, which has a clearly labeled 12v+ and -ground circuit on the same board (clearly identified). Each circuit has it's own ATO blade fuse like an auto fuse box. I have a master inline 40 amp fuse in the 8 gauge wire that feeds the panel.

Wiring wise there is no difference between a fuse and a circuit breaker other then when a circuit breaker blows they can be reset a fuse cannot, you can purchase fuses and circuit breakers for the same amp values. But. how many new boats can you buy that have manufacturer installed circuit breakers? I will give you a hint, not many. I know that technology isn't always the answer but in this case it is(in my opinion), Use Fuses. On the buss supply wire some do some don't, I wire Police cars professionally and I do use a large resetable BREAKER on my main supply wires. The main reason for a resetable breaker is not only for protecting the wiring from the buss to the breaker but also to give me another place to disconnect voltage from the boat. This is the type breaker I use for this application, size depends on the total amps drawn from the buss plus a little bit extra.

With the switch panel with circuit breakers I would have to install a buss bar for both positive and negative circuits to run to the switches and then to the device. more

If you got a ton o' money to spend OR are building some kind of either live-aboard or transoceanic vessel, get breakers. Otherwise go fuses. [links]

With a fuse block I can run the wire from the battery switch to the fuse block and then to the assigned switches and then the device. I can get a fuse block with both a positive and negative buss built in. more

A new panel was needed as the service and equipment were obsolete, not because the fuse pullout needed replacement. But we pose that it may be difficult to find a replacement fuse pull-out for some older fuse panels.

Homeowners should not remove the cover from an electrical panel - it is unsafe to do so. Homeowners should look at their electrical equipment for signs of trouble and should contact a licensed electrician to address any concerns that arise. more
