[tl;dr] If an item of equipment wanted to draw 16A of current, would it be possible for something else to restrict this? i.e. If equipment wanted to draw 16A of current, is it possible it would only draw 10A (hence making it not operate as it should)? Due to something external of the equipment...?
Hi everyone, I'm pretty new here, although I've looked at may posts and threads, this is my first post, so any replies I'll be grateful for!
So... I have a (possible) slight issue that I'm looking for some answers too..
The issue at hand is I have a rig at work, it heats up hydraulic oil and pumps it round a pressurized system. Pretty simple. The issue is, i has been away to be slightly upgraded (from 1.8bar of pressure to 2.5bar of pressure) worled fine for about 4 weeks and now we have a recurring problem, It wont heat up to its desired target (trying for 90degrees, only getting 65 degrees). There are two of these rigs and they are identical, and the issue is with both of them.
Now, onto part two. Where they are installed, is on a large circuit, the rigs use a 32A commando plug (three phase), although the supply is much much larger than that (to provide for alot of other equipment), and there is quiet a high current draw on the main supply that feeds all the circuits (including these 32A outlets).
My first and main thought is obviously that the rigs themselves are faulty after their 'upgrade' and maybe the pump inside it isn't man enough to pump 2.5bar possibly and so it is only the oil in the rig itself that is heating and not the rest of the system. But I wanted to clarify, would there be anything with the install that could possibly prevent this rig from drawing the current it wanted too? For example, if it needed/wanted to draw 16A of current to operate, would there be anything that could restrict it to only being able to draw 10A?
From my experience and knowledge I would have thought not, I would believe the rigs would draw whatever amount of current that they wanted too, if it was too much for the circuit, then the RCCB would trip (FYI, earth leakage isn't an issue here, approx 4mA of earth leakage on this circuit). I don't believe anything would 'throttle' the amount of current available?
Thoughts please!
And thanks in advance to everyone...

- Earth leakage not an issue (at 4mA approx)
- volt drop isn't an issue, it is a short circuit no longer than 15M
- Rig draws approx 10-14A (is on a 32A commando socket/32A 30mA RCCB)
- This install is earthed, although I couldn't account for anything before this circuit as it is owned by an external company, and I don't currently have access to any test certificates of the supply. We have had no other issues with earthing though so I would presume all is good.
Thoughts please!
And thanks in advance to everyone...
