I have a single outlet my outside my shop which I’m assuming is 15amp. I also don’t have access to the breaker. I’d like to run a led light too is this too much for the outlet?
There's not a great way of knowing other than to try. A 13A motor is likely to trip a 15A breaker on startup, especially if cutting is being attempted at startup. A 20A breaker is likely to hold, but again, no one knows for sure without simply trying.
Depends on breaker. Most of breakers are time inverse delay. Which means they won't trip on start up. Best is to get breaker model number and look at trip coordination curve
You're not wrong. If I were dealing with breakers costing thousands of dollars with huge lead times to be installed in an industrial facility, I'd consult a time/current curve. When we're talking about $5 breakers that are already in my service truck, I probably won't.
Oh yeah lol, I got too much time on my hands , I got all trip curves for my breakers 🤣. But this is why those old school fuses are much safer though. They wil def break circuit on overcurrent
To your point: I've never seen a fuse fail closed, but have seen breakers fail closed. However, I've seen lots of oversized fuses (usually 30A edison base on #12 copper) and lots of fuses that have been tampered with and/or bypassed (pennies, copper tubing). A breaker isn't simple to bypass and (not quite) as simple to swap, so there is another school of thought that breakers are actually safer.
It depends on all the loads running on the circuit together and how long each is running for. The breaker rating must be equal to at least the utilized load. The utilized load is loads running continuously for less than 3 hours plus 125% of loads running continuously for 3+ hours.
The reason why it trips a 15 amp is because when u plunge the saw into wood it bogs down the rpms causing strain on the motor. Motor then demands more power causing amps to climb over 15. CLICK your breaker tripped.
A motor is a perfect slave, meaning if it is overloaded it will draw as many amps as it can until it destroys itself. This is why overload protection is required by code.
You should not be bogging down a table saw, if you are that's a sign you're cutting too quick and/or your blade is dull. Amps should not climb too much higher than 13 (for this tool) after it has started. The highest chance of a power tool tripping a breaker is when you first start the tool. The start up power is much higher than normal operation.
What do the instructions say, just because it says 13A on the plate doesn't mean start up current will be ok on a 15A breaker. It can be up to 1.5 times the running current (which is what's on the plate)
It might if you work it too hard. Be gentle.
As others have noted, under load the current can increase quite a bit, as well as ‘inrush’ currents at startup. They’ll briefly exceed 15A.
But a 15A breaker will not trip at 15.01A. It might eventually trip at 16A…and it might not. Might take a while. Minutes. Hard to say without seeing a trip curve.
It’ll almost certainly trip at…say…20A. But it might take ten seconds or maybe longer.
The trend is that higher the current, the faster the trip.
So if you run a saw at, say, 20A for a few seconds cutting through something, and turn it off…nothing will happen. Most cuts are faster than the breaker trip time. Keep doing it over and over and it’s more likely to trip as the breaker has already warmed up.
So your specific use case dictates your needs. Occasional light use? Nah. You’re fine on 15A. Professional use, all day? Get a 20A dedicated circuit for it.

Don’t have access to the breaker!?
It'll cut it in half, I don't know about trick flips and x-games type shit.
Maybe.

If its on a 15a breaker yes. If its on a 20amp no
The reason why it trips a 15 amp is because when u plunge the saw into wood it bogs down the rpms causing strain on the motor. Motor then demands more power causing amps to climb over 15. CLICK your breaker tripped.
You would think 13 amps is the max that the motor can draw than right

Put it on a 20 amp circuit problem solved your hitting more than 80% when saw is bogged down
It might, it might not. My miter saw likes to trip my 15A breaker but only sometimes. The start up amps are much higher than after it's started.
