Fused industrial plugs

[netblindpaul]

Look,
EAWR, & HASAWA are on your side, just prove the muppets are muppets and get them sacked, then get their actions written into the company employee handbook (before they are sacked if needed) for committing acts that endanger others and are criminal, job done.
This will put the other muppets off doing this.
IF, they decide to do it, then they will be sacked also.
Sorted.
People that do such things do not deserve to be employed as they are deliberately risking the lives of others, thus they should not be working.

Dark, I use those in the factory too. They were an easy choice to replace standard commandos. Unfortunately different devices need different levels of protection. If the device uses an internal fuse then they are on those sockets. The devices that use the fuse in the plug are the ones I need help with.
I am moving away from those sockets you showed for a couple of reasons.
1: If the RCD goes I do not want them to reset it without help.
2: They smash easy.
Those I am replacing with the harting Han-e and the RCD MCB in a locked stainless panel next to it.

So the overload protection cannot be in the socket, it has to be attached to the device.

A fuse is O/L protection and S/C ..it dont provide personal protection..so either sack your idiots or fit some sort of protection upfront .... you cant protect any system from idiots trust me I design machine safety and its a minefield of H&S, when they risk losing their job they start respecting the equipment.

I forgot how specific you have to be here =-)

These circuits are all RCCD protected, slowly everything in the factory is being done.

I am doing this for the aforementioned OL/SC protection. Different items plugged in have different OL/SC requirements, so protection must remain with the device.

I could of course provide specific sockets for specific devices, but for obvious reasons don't want to go that route (SO SO much work).


We had one potential lethal mistake last week, just one so it's a good week.

Motor got removed from machine, machine unplugged. signs put all over machine not to use. All operators informed machine not safe, supervisors informed machine not safe to use.

Operators told to remove signs and use machine. Called engineers when it wouldn't start. It didn;t start as the now live motor cables were floating inside the machine.

Failure from everyone involved. The only person getting **** for it was the engineer who forgot to padlock. Serious mistake, but what about the person who ordered the signs removed?

we dont bother with padlocks because they can disappear sometimes.

its much better to remove outgoing from isolator and connector strip ends then close isolator up and padlock.

then its idiot proof, (we then lock isolator on, our isolators interlock and there is no pin etc to get cover off with it switched on)

because of this we then take pic, the only way to connect machine back up is to either cut padlock off or use the key

 

[Darkwood]

The Engineer is solely responsible ... regardless of the employees ignorance this is a situation that should never have occured without the workforce deliberately over-riding lock off and reconnecting wires...if they did then the workforce become liable.

 

[Inteificio]

The engineer is responsible for his part. He is a new guy to the company, a mechanical eng who followed standard practise of his last site.
Serious mistake, but he is not the only one that should be reprimanded.
Engineering manager should have told him our site standard practises.
He should not have left a machine in a dangerous condition.
Instructions to try and activate a machine reported as dangerous should not have happened.

I was just making the point that on this site everything stops with the engineer for everything, it's only our fault most of the time ;-)

Disciplinary action should take care of that.

How does anyone know a drive is isolated? The isolator should be locked in the OFF position. It is then obvious at a glance the drive is isolated.
As for being idiot proof, only an idiot would come up with a system like that.
(Incidentally, how do you padlock the isolator when the locks have gone missing?)

Who authorises cutting a lock off?

I was brought up in the chemical industry where incorrect isolation could be catastrophic.

 

[Inteificio]

I like the bs7671 procedure for isolation.
The only way I differ from my company procedure is I do not use padlocks with the spare key.
The key safe is not secured to suitable standards. If they want to live a circuit I've locked off they need to use bolt croppers. People tend to think twice before doing that.

In event of a really dangerous circuit I will lock it off AND link the outgoing wires. If the circuit is made live a few thousand amp SC in the isolator hints they should leave my stuff alone!

At least, IMO everything should be padlocked with a sign with a phone number on.

Lock off with multiple padlocks, yours, SAPs, engineers etc have had that in the past but if people are cutting them off then you're loosing a battle against Darwinism

As for sockets, if your employer has deep pockets lewden do their metal clad weather tight sockets which are fair robust...just damn expensive. Used a lot of their commando sockets as well but as mentioned all ready, people go to extraordinary lengths trying to pull them out when turned on (I've seen 'Gold card' sparks doing it as well)

 

[Inteificio]

If only there was an option for 'double thanks'.

You solved a lot of problems with that Fin, really helped out.

Thanks.

As well as above you could try Canalis trunking systems they are well made and are fused at the plug and can have track up high or mounted on a wall.
