Should Type A RCDs be a minimum requirement? In partnership with the ECA

This past week, Verso delivered over 100 digital training sessions on Type A RCDs and continued our drive to empower electricians to make the correct installation decisions for modern homes.

Our National Sales Manager Joe Haley had this to say about the training and the topic as a whole:

"I had been wanting to put something together for the wider contractor base for a while, specifically on the issues with Type AC RCCB's and RCBO's and the problems that may be posed following the installation. I am fully aware that many wholesalers are still reaching for Type AC for much of their over the counter business, and the contractor is none the wiser as to why their purchases may pose a problem to not only them. Not only this, but there are still a number of large developers and local authorities including Type AC in there power distribution specification. I personally see this as a huge issue, developers and specifiers are not being informed that what is going into their properties could be life threatening.

The IET wiring regulations can be quite misleading and loose in their terminology on this topic on the topic of selecting RCD's, and in particular the purpose for Type AC. The ECA allowed me to address this to a wide group of contractors across three regions and explain how modern lifestyles, coupled with government targets for carbon emissions should make the industry consider their choice of RCD carefully and make Type A the minimum requirement for residential installations. The section within the regulations referring to selective RCD's only considers Electrical Vehicle Charging and the requirement for a Type A device.

What seems to be ignored are the appliances putting DC back onto the circuit, the sorts that would be familiar with every modern day household. I felt it was important in creating awareness amongst the industry so contractors can not only follow best practise, but use this information for their own benefit when challenging particular specifications. I feel the group that were involved found it very informative and although many were aware that Type AC was an issue, this allowed them to understand why and confirmed the choices that they would be making in the future when installing domestic circuit protection. This is something I wish to repeat to other regions in the near and long term future."
