32 amp 110v transformers

[randytusk]

Hi folks.

I’m planning on a weekend of floor grinding prior to applying resin coat.

I’ve hired a grinder and extraction from a local firm. Who have supplied 110v tools with 32 amp transformers and leads.

Are these ok to run on domestic 13 amp sockets?

My garage breaker instantly trips as it’s max rated for 15 amp.

I think you already have your answer but what plugs are on the input side of the transformers?

[randytusk]

13 amp plug input.

Output is 2 x 16 amp and 1x 32 amp

Can you run the extractor off a separate circuit to the grinder? via extension lead to the house if necessary?

That’s a plan. Upstairs and downstairs might have to be the way.

Other option is to hire a generator for the weekend…..

Are both items your using 110 Volt?

[randytusk]

Yes.
110v 32 amp dust extraction and 110v 32 amp grinder

It's not the amp rating of the transformer that should matter, it's the power drawn by the tool.

Does the transformer trip the circuit with the tool switched off, or not plugged in to the transformer?

Is the tripping overcurrent or an earth/leakage fault?

Can you plug it in to a ring main with a 32A breaker?
It could be a matter of the current surge to start the motor is tripping the garage breaker.
For a big motor, you'd often choose a 'C curve' circuit breaker which trips more slowly.

If you have one, try plugging it in to the cooker socket.

Sadly don’t have one.

Local hire place is open tomorrow- maybe a diesel generator is in order?

Bear in mind that 110v 32 amp is 14.6 amps at 240v

The breaker protecting the circuit will likely be 20 amp plus.

It will be fine

It isn't fine, read the OP.....

The dust extractor is unlike to be 16a at 230v (correct uk voltage). The extractor would normally be just under 8amps
This should work fine with the grinder on a 32 amp ring.

I have an old Bosch 9 inch grinder that trips the breaker sometimes when you start it. It’s happened on different circuits and different houses so i know its the tool. No soft start. Just POW ! Full throttle , you need to hold on tight with both hands as it has some torque steer on it

Is it when you turn it on ,or after using it for a while ?

Like others have said try a different circuit.

^^ This is the question that needs answering.
