Help understanding Electrical for Clarke Vacuum Former
I recently bought a used Clarke Vacuum Former. It came with a 30 amp 125v plug. I am going to wire up an outlet for the machine but want to make sure this is the correct plug.
This is the data sheet from the company. http://crclarke.com.au/crclarke/imag...cument/750.pdf
Should I use a 30 amp breaker? Should I continue using the 30 amp plug?

Re: Help understanding Electrical for Clarke Vacuum Former
after down loading the manual it looks like there is some errors that you may want to contact Clarke about
on page 3
All 220-240V machines are fitted as standard with BS 1363A 13A moulded
on plug
which is OK for the UK
but it then goes on to say :-
110-120V machines will require a plug to conform with BS 4343 for low voltage
supplies, a 1000VA supply will be required.
on page 16
you have -
Electrical
Voltage 220-240
Current (max) 11A
VA (Total) 2650
VA - Heater 2400
VA - Vac pump 250
Circuit Protection - Heater 12A Circuit Breaker
Circuit Protection - Vac Pump 5A Circuit Breaker
Circuit Protection - Control 0.5A Circuit Breaker
I would of expected the 120V version to take 2650 as well
there for the supply current = 2650/120 = 22A
that's 2.64 times the current you expect using the 1000 VA from page 3 !

I just plug it into a 110 outlet and it turned on, however heaters wouldn't get hot and the pump wouldn't run.
If I unattach the plug that came with the machine would you be able to tell its a 220 or 110

Re: Help understanding Electrical for Clarke Vacuum Former
provided no one has changed the mains cable
the 120V version has green , black and white wires
the 240V version has green/yellow , brown and blues wires
as a double check
have a look at the vacuum pump it should have a label showing the required supply voltage
have you checked the circuit breakers are all closed
( mechanical shock as you moved the machine could of tripped them )

Re: Help understanding Electrical for Clarke Vacuum Former
I looked at the Plug. It has three wires. Black, White and Green. This means it should work in a regular outlet around the house? Or, does a 110 outlet have to be hooked up to a 30 amp breaker and nothing else running on it?

Re: Help understanding Electrical for Clarke Vacuum Former
assuming the 120V machine takes 2650VA like the 240V version
you need to use an outlet that can supply 22A

Re: Help understanding Electrical for Clarke Vacuum Former
I would very much doubt that the 240v machine would draw twice the current.
I would think its still about 10 amps as the 120v.

Re: Help understanding Electrical for Clarke Vacuum Former
the 120V and 240V versions must have the same heating power and I'd expect they can use the same 120V heaters
all wired in parallel for the 120V version and a series / parallel combination for the 240V version
with 4 heating zones I'd expect they used eight 300W elements
in the case of a resistive load like the heaters the 2400 VA = 2400 W as the current taken is in phase with the voltage
for the 240V heater the current is 2400 divided by 240 = 10 A
for the 120V version the current is 2400 divided by 120 = 20 A
