Bathroom Works

[bryn]

Guys can you give me some advice on the items below as this Part P confuses me sometimes.

1) client wants bathroom fan changing has no isolator on fan supply from light switch and CU not RCD protected.

I intended to replace Fan and install pull switch as isolation switch do i need to rcd protect as i have changed circuit and is it notifiable have assesment soon so need to get it right.

2) Client installing under floor heating mat I am aware thermostat not allowed in bathroom and has to be rcd protected does it need to be seperate circuit or can you spur from ring which is rcd protected to clock and thermostat in external position to bathroom.

1. If you where just replacing the fan, then I believe as it is "like for like" it would not need to be RCD protected. However if you are adding an isolator then you are modifying the circuit. Therefore i believe you would have to RCD protect the circuit.

2. Depends on the size of the mat. Ideally on its own circuit. However if its a small mat, on the first floor (no kitchen as part of the ring) then I believe there will be no problem taking a spur off the ring.

pretty much as above. if you modify the circuit, it requires RCD & notified. if you replace, no certs or part p

for UF heating, bathrooms are usually small units (around 3-500w). so can go on the ring provided its not already near capacity

i would say

1 needs rcd and notifiable, unless you swap the fan like for like and nothing else.

2 depends on the load of the underfloor heating

Just change the fan like for like,,, it's maintenance so no RCD or isolator required... if you did fit an islator then the circuit would need RCD protection

the size of the heat mat will determine if it needs it's own circuit or not.. the thermostat usually has a programmer combined in it;s functionality

Just to add I understand underfloor heating is notifiable also, wherever it is installed.

Going back to the OP:

As the works include extra electrical items in the bathroom (and the introduction of a new circuit to that location), isn't anyone going to mention the requirements of supplementary bonding?
