Been to have a quick look at a possible job . Five pin point putting in to feed waste compactor . The nearest board it could come off is a bout a120 meters run . Took a earth loop test at board 0.55 . If I ran 10mm 5 core am in ok for volt drop and a calculated earth loop of 0.99 (could be a...
Hi everyone
ive got my AM2 coming up and im unsure about the over load settings for the D.O.L, ive seen 2 different equations and im trying to work out which is right.
so say my motor is 750w would my calculation be 750/400/1.732/0.8 = 1.35
or
750/400 x 1.732 x 0.8 = 2.59
i bought a course...
Hi all,
I am trying to diagnose an issue with a BEKO WMB101433LW washing machine where it was reported (by the missus) that the drum has far more resistance than usual.
I've ruled out bra wires etc and anything between inner and outer drum and have isolated the issue to the high torque setting...
I have a DOL starter (https://docs.rs-online.com/c08c/0900766b81586106.pdf for reference) that I want to connect to my ac motor. I understand that the dol starter has a built-in contactor. I want to connect two other switches, a tilt and a proximity switch. Is it possible to connect these two...
Hi guys,
Since this winter, I realized that the batteries on my cars have outlived theirs, I decided that I needed to take new batteries, but later I found such a thing as a starter, does anyone use them? what kind of feedback can you give? Then I read about some models and selected a couple of...
I hope someone can help me understand this. I've just replaced both my florescent tube lights with Energizer LED tubes, and they were fine for about a week but last night the starter fuse in the kitchen light blew. This afternoon I swapped in the starter from the other light and it too...
Hi all
I would like a bit of advice to do with a DOL starter ill be fitting. Basically I'm replacing an old water damaged crabtree DOL starter with a new mcg DOL starter. The old coil was pulled in via a single channel heating timeclock and the new one will need to be too. The old DOL just had...
Renault clio mk2 not cranking over. Battery reading good voltage. Changed starter motor for new one but same issue. Bench tested old starter and working fine. Noted that when I place jumer cable on negative battery terminal and then to engine to ground it starts not problem. I've taken off the...
Recently changed my starter relay on my xv1600 wildstar. When reattaching battery cable, it caught a small thermostat and sparked. Now whilst I have power to the relay from the battery I have nothing beyond the relay and turning the key does nothing. All fuses have been double and treble...
My 92' Firebird that I just acquired will not start. I bypassed VATS security
with resistors so the security light now shuts off. I replaced my positive
battery lead that was shot and the only thing that happens when I turn the
key is the temp gauge fluttering. The relay only has 0.5 constant...
Hi all,
I’m trying to repair my potato peeler and have spotted this little burned out capacitor inside. I noticed the melting in the top corner which also melted away some of the wire touching it.
These capacitors I’m having trouble finding. It has the resistor at the top also.
Anyone help...
I've got a call about a pump that is not working. It was a 30 kw motor with a star delta starter. The motor start but before it changes to delta it trips. And it look like the motor is single phasing. So i disconnect both cables at the motor and start it again. As soon as the delta contactor...
Hi, I kinda think I know the answer to this but will ask opinion anyway. I am fitting a new compressor pump and motor to my receiver and have bought;
twin cylinder pump;
3hp motor (2.2kw)
Although, the motor looks like this
So, I upgraded the ring main that the compressor will use in my...
Hello everyone,
Does anyone have any information on how much current does a car starter motor draw at no load? The motor specs:
Power max: 1.4kW
Voltage: 12VDC
Armature resistance: 0.7 ohm
Brand: Bosch
Model No.: 1740374
The starter was removed from the engine when tested.
A little history...
Does it matter which part of the coil power is supplied? (can you reverse polarity)? For example can I put the “hot” current carrying conductor on terminal A2 and leave with a grounded conductor from terminal A1 (assuming power supplieD is 120v.) (what about 24V?) Is there a specific type of...
Hi, I removed a start capacitor (burnt out) from my newly acquired bandsaw and did not take a photo of where to replace wires. Apart from the earth there is on left a brown with opposite black/red, next terminal is blue and blue, next is a white with nothing opposite. This junction box is on the...
I have a 2004 F-150 STX 2WD with the 4.6L that I inherited from my grandfather this past winter. About 2 months ago, it had a really hard time shifting out of park, so I left it neutral with the keys in it. This naturally drained the battery, so I would just jump it off once a week and let it...
