Hi. This might sound like a silly question but I am a novice when it comes to electrical related matters.
I have put up a market stall in one of the local events. I have 5 electrical equipments requiring 10Amp power and 2 requiring 5Amp. The organiser has provided a 10Amp and a 15Amp connection.
Am I correct in my thinking that I can only use 2 10Amp and a 5 Amp equipments and anything more will trip the connection?
Or could I put some extension box to connect more or all equipments in those two connections?

I have 2 of these twin basket things:

Yeah these won’t be using power continuously. Will draw full power until oil heats up, then only uses it to maintain the temperature which will be a lot less power hungry.
If you are worried, you can supplement with a genset.

They are 'dumb' heaters so it's either full power or none at all. That means if both baskets are heating up, he will trip the circuit.
He can heat up each basket one at a time, but if he then leaves both baskets connected, if they both happen to turn on again at the same time to maintain the temperature, he'll be over the current limit and trip the breaker.

Whoops, I should have clarified, one at a time per circuit.
That will be fine, just don't turn it all on at the same time. Modern mobile kitchens have smart switching technology that lets the computer decide which devices to power at which time. (i.e. it will power your fridges down, whilst you are warming up your fryers), but you can manually do the same thing if you only have 7 devices. Just remember that the 15 Amp plug has a slightly larger earth prong so you may not be able plug straight into it without a 15 to 10 adaptor, or is it the other way around (10-15) that causes the issues?
What? So separate appliances can talk to each other without any wifi or other connection and work out which ones turn on when without any sort of setup ?
Can you give me an example of such a system?

Judging from this, I don't think OP has a modern mobile kitchen. :)
@Krankite: My point is that OP would know if he had something like that and would have said he has one.

CZone digital switching is the ultimate solution for uncomplicated control of your system. You can control all switchable functionality inside the system from a single screen (in either 1 or 2 locations) or from an iPad, thus changing the state of the vehicle with a single touch. Essential information like voltage, current and fusing is available in a split second.
@HighAndDry: I don't doubt these things exist but if OP had one he would know and would be asking this sort of question
@[Deactivated]: Oh yeah I don't think OP has one of these - I think the comment you first replied to was saying that the existence of these systems (that allow you to plug, say 25A worth of equipment into 15A of powerpoints) means that you can do the same thing by managing their electrical load manually. So in regards to OP's question of:
Am I correct in my thinking that I can only use 2 10Amp and a 5 Amp equipments and anything more will trip the connection?
They can use more than 2 x 10A + 1 x 5A pieces of equipment, so long as they're not all running at full load at the same time, and so only drawing no more than ~15A total.
Also consider the possibility that the ebay seller/manufacturer is lying about the power consumption and the heaters are far less powerful than they claim…
It's easy enough to test the consumption at home. Just look for a power circuit on your switchboard that uses 15Amp breakers and connect 2 of them to it. if it doesn't blow you should be alright.
Alternatively if one wants to be extra-sure, a $15 power meter like this will give you the actual usage in watts.
It's 60 amps and 14+kw
Basically you cannot run all of those on the power given.
Really depends on the equipment. Theorectically you can only run 2x10amp and 1x5amp pieces, but it "can" be worked around depending on when they draw that much power.
A lot of motors have a high startup draw and then drop back.
What are you running? 40amps is a lot of power. That's nearly 10kW of power.
