What RCD for10.5 shower electric

Asked by: Lotto
Hi Lotto, 10.5kW requires 43.75A at 240V, so you would need to go up to at least our 63A rated model (ScrewFix catalogue code 56472).

can this be used as a standalone device for a shower pump?

Asked by: stdeight
Hi stdeight, As long as your shower is running at less than 9.6kW (9600W) then this would be a suitable load for the device. If your shower is over this consumption then you would need to up-rate the device to our 63A version.

Dimensions

Hi, can you tell me if the 40A & the 63A have the same phisical dimensions? Thanks Martin
Asked by: MDdd
Hi, thank you for your product enquiry. Yes, all BG RCDs are a standard set of dimensions, the same as the Main Switch in all but height (out of the consumer unit front).

Do you have, in stock, a suitable containment unit for this item? IP56 would suffice.

I want to mount the device in house and use it to provide a supply to external garden sockets and lights.
Asked by: Chalkperson
Hi, thank you for your product enquiry. The British General 5-Module 3-Way Populated Garage Consumer Unit (1926G) comes with this very model of 40A 30mA RCD, plus a 32A MCB and 6A MCB included and is rated IP65.

is this item also a 40A mcb (fuse) or do I need to fit a separate 40A mcb between this and the shower

Asked by: USEDNICKNAME
Hi, thank you for your product enquiry. This is an RCD only, so you would need a separate MCB to complete the protection. One thing to check before you go ahead is the power level of the shower, as a 40A device is good for 9,600W maximum (9.6kW) so if your shower is more powerful you would need a higher rated pair of devices.
