![]() ![]() ![]() You will need GFCI protection for most, if not all, circuits in the shed. A 100A breaker (especially if bundled with a panel) can be used even if the feed is a 50A breaker with 50A-rated wire. That main breaker can be any size from the size of the feed breaker in the main panel on up. You will need a disconnect switch at the shed - that can be a separate switch but it is often cheaper and easier to use a main breaker in the subpanel. But far better is a big panel, often listed as a "main panel". The subpanel can be a small subpanel, like you may have had for your hot tub. In addition, buried cable has to be buried deeper than conduit with individual wires.įor your use, you will need 3 main wires - 2 hots and a neutral - and, unless you are using appropriate metal conduit, a ground wire. However, for outside and/or buried use, only certain cables will meet code. The wires can be individual wires in conduit or can be a cable with all the wires together. There are a number of tables available showing wire sizes - beware that there are a few gotchas to look out for, so ask here before buying the wire, just to make sure it will work. But even though the aluminum is physically larger, it is often much cheaper. By equivalent, I mean that the physical size (AWG) for a particular current (Amps) for copper will be smaller than the physical size of aluminum wire for that same current. You can often (especially with current copper prices) find large aluminum wires available for less than equivalent copper wires. That is because most panels and breakers (unlike receptacles, etc.) are rated for use with both copper and aluminum. ![]() You can, generally, use copper or aluminum wire when going between panels. With most panels, larger breakers cost very little until some particular point - typically somewhere around 100A or so the price will double or triple (or more). Or you may be able to use a larger breaker. The breaker in the main panel can be the existing 50A breaker. Always be sure to consult a licensed electrician before DIY electrical work.This is absolutely doable. You will have to be careful when adding outlets for a 15 amp breaker. Another aspect to consider to whether or not they will all be switched on together at the same time. Household devices are required to run at 110-125 volts and most are rated at 115 volts so 1725 watts for a 15 amp cord or circuit. The amount of lights and outlets that can be installed to the breaker box will depend on the wattage and amperage that is drawn by each light. Lights and outlets are normally wired on separate branch circuits, which means that the lights will be protected by a separate circuit breaker to the one which protects the outlets. Generally, homes have eight to 10 outlets on a 15 amp breaker but not all are used at the same time. For example, if you plug in an appliance that uses 15 amps then you cannot use another appliance that takes up 10 amps or will you blow the circuit. This is because the number of outlets on a 15 amp or 20 amp circuit depends entirely on what you plug into those outlets and how much wattage and amperage it uses. It is dependent on the wattage of the lights. If you have a 15 amp breaker, or a 20 amp breaker, there is not a specific number of lights and outlets that can go on it. It is best to have a certified, trusted electrician to assist with any electrical work. Overloading a 15 amp breaker can lead to very dangerous situations. The only issue with relying on this formula is that it is advisable to only load a breaker up to 80 percent of its capacity. On average, a 15 amp breaker can run a one 1K light each without blowing or about 1800 – 2000 watts. But how many watts can you put on a 15 amp breaker? As beautiful as Christmas lights are, they can cause a trip in the breaker or an outage if you overload the breaker. ![]() How Many Watts Can a 15 Amp Breaker Hold?
